Question

find the volume of a cone with a base diameter of 8 yd and a height of 9 yd
use the value 3. 14 for pie and do not do any rounding

​

Answer 1

Answer:

V = 150.72 yd³

Step-by-step explanation:

To find the volume, we will need to use the formula  $V = \frac{1}{3}bh$

To find the base, we will need to use the volume of a circle, which is $A = \pi r^{2}$.

If the diameter is 8, the radius is half which is equivalent to 4. Put this into the equation:

A = π4²

A = 16π ≈ 50.24.

Now, use this in the Volume of a Pyramid formula:

V = 1/3 (50.24 ·9)

V = 150.72 yd³
