If the volume of a cylinder is 900 cm squared with a height of 20 cm, what
is the diameter of the cylinder? Round to the hundredths.

Answers

Answer:

The diameter is 7.6 cm

Step-by-step explanation:

Mathematically, the volume of a cylinder can be calculated using the formula;

V = pi * r^2 * h

From the question;

V = 900

r = ?

h = 20

Substituting these values

900 = 3.142 * r^2 * 20

r^2 = (900)/(3.142 * 20)

r^2 = 14.32

r = √14.32

r = 3.78 cm

Mathematically, the diameter is 2 times the radius

We have this as;

2 * 3.78 = 7.6 cm

Find the unit rate. Ryan can mow 3/5 of the yard in 2
hours. How much of the yard can Ryan mow in one hour?

Answers

Answer:

3/10 of the yard in one hour

Step-by-step explanation:

[tex]3/5(1/2)=3/10[/tex]

Answer:

3/10 of the yard.

Step-by-step explanation:

What we know:

Ryan can mow 3/5 of a yard in 2 hours.

What we need to know:

How much of the yard Ryan can mow in 1 hour, so the unit rate.

How do we do this:

It's simple if you think about it.

Just divide 3/5 by 2 (or multiply by 1/2)

3/5 * 1/2

3/(5*2)

3/10 of the yard can be mowed in one hour.

Step-by-step explanation:

the diagram shows a circle in a square 6cm calculate the shaded area take pi to 3.142

Answers

The question is incomplete (as there's no attachment to support the question).

However, I'll base my calculations base on the attached diagram to this solution.

Answer:

Shaded Area = 7.722 cm²

Step-by-step explanation:

Given.

Side of the square = 6cm

π = 3.142

Required:

Area of shaded region

First, the area of the square needs to be calculated.

Area of a square = Length * Length

Area = 6cm * 6cm

Area = 36cm²

Then we calculate the area of the circle.

To calculate this, we need to get the radius of the circle.

If the length of the sides of the square is 6 cm, then the diameter of the square is also 6 cm.

Now that we have the diameter, the radius can be calculated.

Radius, R = ½D (where R and D represent radius and diameter, respectively)

So,

R = ½ * 6 cm

R = 3cm

Area of a circle = πr²

Area = 3.142 * 3²

Are = 3.142 * 9

Area = 28.278 cm²

The shaded area is then calculated by subtracting the area of the circle from the area of the square.

Shaded Area = Area of Square - Area of Circle

Shaded Area = 36cm² - 28.278cm²

Shaded Area = 7.722cm²

Hence, the shaded area 7.722 cm²

The question is incomplete (as there's no attachment to support the question).

However, I'll base my calculations base on the attached diagram to this solution.

Answer:

Shaded Area = 7.722 cm²

Step-by-step explanation:

Given.

Side of the square = 6cm

π = 3.142

Required:

Area of shaded region

First, the area of the square needs to be calculated.

Area of a square = Length * Length

Area = 6cm * 6cm

Area = 36cm²

Then we calculate the area of the circle.

To calculate this, we need to get the radius of the circle.

If the length of the sides of the square is 6 cm, then the diameter of the square is also 6 cm.

Now that we have the diameter, the radius can be calculated.

Radius, R = ½D (where R and D represent radius and diameter, respectively)

So,

R = ½ * 6 cm

R = 3cm

Area of a circle = πr²

Area = 3.142 * 3²

Are = 3.142 * 9

Area = 28.278 cm²

The shaded area is then calculated by subtracting the area of the circle from the area of the square.

Shaded Area = Area of Square - Area of Circle

Shaded Area = 36cm² - 28.278cm²

Shaded Area = 7.722cm²

Hence, the shaded area 7.722 cm²

There is a greater correlation between the IQ scores of identical twins raised together than for fraternal twins raised together. What conclusion can be drawn from this data

Answers

Answer:

This correlation simply means that, in every twin whether identical or fraternal twins, there is a relation between their IQ scores and when they are raised together.

Regarding to the test carried out, it showed that, when an identical twin is raised together, their IQ score tends to be higher in direct comparison with a fraternal twin that was raised together. That is, if the fraternal twin IQ is 100, then, the identical twin IQ is going to be above 100 (probably around 120)

A. There are not enough numbers after the decimal.
B. The sum of 7,294 and 3,647 is incorrect.
C. He left out the place holder under the 4.
D. He multiplied incorrectly

Answers

Answer: The correct option is B-He left out the place holder under the 4.

Step-by-step explanation:

Consider the provided multiplication.

Jared need to multiply 36.47 with 12

The correct multiplication should be:

36.47

× 12

7294

36470

43764

Now consider the Jared's work he just left out the place holder under the 4.

Because it is not just 1×36.47 it is actually 10×36.47, so he needs to add a zero under the number 4.

Q.1. Base and height if a parallelogram 12 cm and 8 cm respectively. Find its area.

Answers

Answer:

Area of the parallelogram is 96 [tex]cm^{2}[/tex].

Step-by-step explanation:

A parallelogram is a quadrilateral with parallel and equal length of opposite sides. The diagonals are perpendicular to each other.

Area of a parallelogram is given as,

Area = base x height

Thus for the given parallelogram with base 12 cm and height 8 cm, the area would be;

Area = base x height

= 12 x 8

= 96

Area = 96 [tex]cm^{2}[/tex]

The area of the parallelogram is 96 [tex]cm^{2}[/tex].
