Question

What is the volume of the cone to the nearest cubic meter with radius of 4m and height of 5m
A) 21 m^3
B) 84 m^3
C) 168 m^3
D) 335 m^3

Answer 1

Answer :

B) 84 m³

Step by step :

$\boxed{ \bold{volume = \frac{1}{3}\pi {r}^{2} h }}$

$volume = \frac{1}{3} \times 3.14 \times 4 \times 4 \times 5 \\ volume = \frac{1}{3} \times 251.2 \\ volume = 83.73 \: {m}^{3} \\ volume = 84 \: {m}^{3}$
