Question

What’s the volume of this cone?

Answer 1

volume = (1/3) * π * r² * h

= 1/3* 22/7 * (3.5*3.5) * 5 ( 22/7 is the value of π)

=64.1

Answer 2

Answer:

If you need a pi in your answer: 20.417 $\pi$ (rounded to the nearest thousanth)

If you don't: 64.141 (rounded to the nearest thousanth)

Step-by-step explanation:

The formula of the volume of a cone: $V = \pi r^2\frac{h}{3}$

--> V = Volume, r = Radius, h = Height

In other words, the volume of the cone is the area of the circle x height x 1/3 x pi.

Since the radius of the cone is 3.5, you square that number.

--> (3.5)^2 = 12.25

The height is 5, so h/3 will be 5/3.

The volume = $\pi$ x 12.25 x 5/3

--> 20.416666... $\pi$

--> 64.14085....
