Alright, lets get started :

The area of sector is = 1/2 θ r^2 where θ is in radians

So lets first change our given angle θ ie 40 degree into radian.

For changing degree to radian, we multiply 40 * Pi/180 = 0.698 radians

Now lets plug the value in formula

Area = 1/2 θ r^2

Area = 1/2 * 0.698 * 15^2

Area = 78.54 square inches : Answer

Hope that will help :)

In degrees, the area of a sector is

A=\frac{\theta}{360}*\pi   r^2

Since our central angle is 40 degrees, and our radius is 15, our formula will look like this:

A=\frac{40}{360}*(15)^2\pi and

A=\frac{40}{360}*225\pi. Not sure how far you need to go with this as far as reducing or solving, but that's the formula. The actual area is \frac{225\pi}{9}, or in decimal form 78.54 rounded

What is the volume of the cylinder below? A cylinder with a height of 12 millimeters and diameter of 18 millimeters. 108 pi mm3
Artemon [7]

Answer:

V =972 pi mm ^3

Step-by-step explanation:

The diameter is 18 so the radius is 1/2 of the diameter

18/2 = 9

r=9

The volume of a cylinder is

V = pi r^2 h

V = pi (9)^2 12

V =972 pi mm ^3
