find the curved surface area and total surface area of a right circular cylinder whose height is 15 cm and radius of the base is 7 cm​

Answers

Answer 1

Answer:

[tex]CSA = 660cm^2[/tex] --- Curved Surface Area

[tex]TSA = 968cm^2[/tex]  --- Total Surface Area

Step-by-step explanation:

Given

Shape: Cylinder

[tex]h = 15[/tex] -- height

[tex]r = 7[/tex] --- radius

Solving (a): The curved surface area (CSA)

This is calculated as:

[tex]CSA = 2\pi rh[/tex]

This gives:

[tex]CSA = 2 * \frac{22}{7} * 7 * 15[/tex]

[tex]CSA = 2 * 22* 15[/tex]

[tex]CSA = 660cm^2[/tex]

Solving (b): The total surface area (TSA)

This is calculated as:

[tex]TSA = 2\pi r(h + r)[/tex]

This gives:

[tex]TSA = 2 * \frac{22}{7} * 7 * (15 + 7)[/tex]

[tex]TSA = 2 * 22 * (15 + 7)[/tex]

[tex]TSA = 2 * 22 * 22[/tex]

[tex]TSA = 968cm^2[/tex]

Given 10 is a leg of a right triangle and 11 is the hypotenuse, what is the length of the other leg of the right triangle? Round
Vou answer to the nearest hundredi derinals

Answers

Answer:

The length of other leg is 4.58

Step-by-step explanation:

It is given that:

One leg of triangle = 10

Hypotenuse = 11

Using Pythagorean theorem,

[tex]a^2+b^2=c^2\\(10)^2 + b^2 = (11)^2\\100+b^2 = 121 \\b^2 = 121-100 \\b^2 = 21[/tex]

Taking square root on both sides

[tex]\sqrt{b^2}=\sqrt{21}\\b=4.58[/tex]

Therefore,

The length of other leg is 4.58

Point A, located at (-11, - 7) on the coordinate plane, is reflected over the x-axis to form point B. Then point B is reflected over the y-axis to form point C. What are the coordinates of points B and C?​

Answers

Answer:

Answer: B(-11,7) C(11,7)

Step-by-step explanation:

Reflections In The Coordinate Plane

Reflect over the x-axis:

When we reflect a point over the x-axis, the x-coordinate remains the same, but the y-coordinate is mapped to its opposite.

The reflection of the point (x,y) over the x-axis is the point (x,-y).

Reflect over the y-axis:

When reflecting a point over the y-axis, the y-coordinate remains the same, but the x-coordinate is mapped to its opposite (its sign is changed).

The reflection of the point (x,y) across the y-axis is the point (-x,y).

Point A is at (-11,-7). When reflected over the x-axis, it maps to Point B located at B(-11,7).

Point B is now reflected over the y-axis and maps to C(11,7).

Answer: B(-11,7) C(11,7)

Consider an example of an apartment: The number of bedrooms, bathrooms, and the floor of an apartment determines its price. Which is the dependent variable in this example

Answers

Answer: The price of the apartment.

Step-by-step explanation:

We know that for a given apartment, the number of bedrooms, bathrooms, and floor determines the price.

Then we could define the variables:

x = number of bedrooms.

y = number of bathrooms

z = floor.

And define the price of the apartment as a function of these variables:

p(x, y, z) = price

Then the independent variables are x, y, and z.

And the dependent variable (this is, the variable that changes in response to the changes in the independent variables) will be the price of the apartment.

Using function concepts, it is found that the dependent variable in this example is the price.

The standard format of a function is: [tex]y = f(x)[/tex].In which each value of y is a function of one value of x, and thus, x is the independent variable and y is the dependent variable.

In this problem, price depends of the number of bedrooms, bathrooms, and the floor of an apartment, hence, the function is:

[tex]p = f(be, ba, fl)[/tex]

Which means that the dependent variable is the price.

What is the diameter of the inscribe circle of the triangle?

Answers

Answer:  42

============================================

Work Shown:

The two angle bisectors intersect to form the incenter. The incenter is the center of the inscribed circle (aka "incircle"). This circle is the largest possible, but is completely inside the triangle. No portions of the circle spill outside the triangle.

The two segments marked with lengths x+8 and 2x-5 are two radii of the incircle. This is because the sides of the triangle are tangent to the incircle.

Since all radii are the same length, we can set those expressions equal to one another and solve for x

x+8 = 2x-5

x-2x = -5-8

-x = -13

x = 13

This x value then leads to

x+8 = 13+8 = 212x-5 = 2*13-5 = 26-5 = 21

Both radii are 21 units long, which helps confirm we have the proper x value. We double the length of the radius ot get the diameter.

So the diameter of the incircle is 2*21 = 42 units long.

Which expression is equivalent to this expression (x-1)-(1-x)+x
