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

  • <em>r</em> is radius
  • <em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

Radius <em>r</em> = 4

Height <em>h</em> = 21

<u>Step 2: Find Volume</u>

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