The inner diameter of a circular well is 3.5 m. It is 10 m deep. Find
(i) its inner curved surface area
(ii) The cost of plastering this curved surface at the rate of Rs. 40 per m².​

Answer:

It looks different. Can you provide some formulae based on it. I may help you out in the comment section!

The diameter of the circle is 48 in.

A circle's sector is a pie-shaped portion made up of the arc and its two radii. At both ends of the arc, when a section of the circle's circumference (also known as an arc) and two of its radii meet, a sector is produced. A sector of a circle resembles a piece of pizza or a pie in shape.

As per the given data:

Central angle of the sector (θ) = 30°

Area of the sector (A) = 150 in²

A = (1/2) × r² × θ {where θ is in radian and r is radius}

Converting 30° to radian.

= 30 × (π/180)

= π/6

150 = (1/2) × r² × π/6

r = √(1800/π)

r = √(576)

r = 24 in

Diameter = 2r

= 2 × 24 in

= 48 in

Hence, the diameter of the circle is 48 in.

Step-by-step explanation:

Answer:

y = x + 6

Step-by-step explanation:

Line is passing through the points (0, 6) & (1, 7)

So, y-intercept (b) = 6

Slope (m) [tex] =\frac{(7 - 6)}{(1 - 0)} = \frac {1}{1} = 1[/tex]

Equation of line in slope-intercept form is given as:

y = mx + b

Plugging the values of m and b in the above equation, we find:

y = 1*x + 6

y = x + 6

Answer:

Number of people in the conference on first day = 45

It increased by 40% the second day.

To find:

The number of people in the conference on second day.

Solution:

The conference had 45 people and it increased by 40% the second day. So,

Number of people in the conference on second day [tex]=45+40\%\ of\ 45[/tex]

                                                                                        [tex]=45+\dfrac{40}{100}\times 45[/tex]

                                                                                        [tex]=45+18[/tex]

                                                                                        [tex]=63[/tex]

Therefore, the number of people in the conference on second day is 63.

Answer: 12 ounces

Step-by-step explanation:

Let the ounces of fruits that should be added be represented by x.

Based on the information given in the question, this can be represented by:

3/2 = 18/x

Cross multiply

3 × x = 18 × 2

3x = 36

x = 36/3

x = 12

Therefore, 12 ounces of nuts should be added.

The length of XY is 8.

When a triangle has precisely the same three sides and precisely the same three angles, it is said to be congruent.

Given that, the triangles ΔXYZ and ΔMNL are congruent.

Therefore, XY≅MN.

Since MN = 8, it follows XY =8.

Hence, the length of XY is 8.

Answer:

a. 120 degrees

b. 2.0944 radians

Step-by-step explanation:

From 12:00 to 12:15 there forms a 90 degree angle. If we divide this by 3 we get that every 5 minutes the hand moves 30 degrees. Since in this scenario, the minute hand moved from 12:10 to 12:30 it, therefore, moved a total of 20 minutes so we can do the following math

20 / 5min = 4 times

4 * 30 degrees = 120 degrees

We can see that in this time it moved a total of 120 degrees. Now we can use this value to turn it into radians using the degree to radians formula

degrees * [tex]\pi /180[/tex] = radians

120 * [tex]\pi / 180[/tex] = radians

2.0944 = radians

Answer:

Answer:

314.2 cm²

Step-by-step explanation:

The area of the circular cross section of the pipe is given by A = πd²/4 where d = diameter of pipe = 20 cm

So, A = πd²/4

substituting the value of d into the equation, we have

A = π(20 cm)²/4

A = π400 cm²/4

A = 100π cm²

A = 314.16 cm²

A ≅ 314.2 cm²
