Volume of a Cone Formula: $\displaystyle V = \frac{1}{3} \pi r^2h$

r is radius
h is height

Step-by-step explanation:

Step 1: Define

Radius r = 4

Height h = 21

Step 2: Find Volume

Substitute in variables [Volume of a Cone Formula]: $\displaystyle V = \frac{1}{3} \pi (4)^2(21)$
Evaluate exponents: $\displaystyle V = \frac{1}{3} \pi (16)(21)$
Multiply: $\displaystyle V = \frac{16 \pi}{3}(21)$
Multiply: $\displaystyle V = 16 \pi \cdot 7$
Multiply: $\displaystyle V = 112 \pi$
