Question

Find the volume of a cone with a diameter of 12.9 cm and a height of 16.6 cm.

Answer 1

Answer:

112cm^3

Step-by-step explanation:

Formula for volume of a cone is:

$\frac{1}{3} \times \pi \times {r}^{2} \times h$

r = radius and h = height

To find the radius you divide the diameter by 2:

12.9 ÷ 2 = 6.45

Now substitute values into the formula:

$\frac{1}{3} \times \pi \times {6.45}^{2} \times 16.6$

Which equals 112cm^3
