Question

What is the volume of the cone shown above ? If H = 2 and R= 9

A. 18 units cubed
B. 169.6 units cubed
C. 162.5 units cubed
D . 54units cubed

Answer 1

For this case, the first thing you should do is apply the following formula:
V = (pi * r ^ 2 * h) / (3)
Where,
r: radio
h: height
Substituting values we have:
V = (3.14 * (9 ^ 2) * 2) / (3)
V = 169.56
Rounding:
V = 169.6 units ^ 3
Answer:
the volume of the cone is:
B. 169.6 units cubed
