Answer:

x = 3

Step-by-step explanation:

10x + 2 = 32 ( subtract 2 from both sides )

10x = 30 ( divide both sides by 10 )

x = $\frac{30}{10}$ = 3

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 = 12

Height h = 71

Step 2: Find Volume

Substitute in variables [Volume of a Cone Formula]: $\displaystyle V = \frac{1}{3} \pi (12)^2(71)$
Evaluate exponents: $\displaystyle V = \frac{1}{3} \pi (144)(71)$
Multiply: $\displaystyle V = \frac{1}{3} \pi (10224)$
Multiply: $\displaystyle V = 3408 \pi$
