Answer 2

Answer:

34650 cm^3

Step-by-step explanation:

Given, Circumference of Base = 1.32 m = 132 cm

Height = 25 cm

Step 1: Find Radius

$2\pi r = 132$

$r = 132 * \frac{7}{22} * \frac{1}{2}$

By cancellation,

$r = 3 * 7 * 1 = 21 cm$

Step 2: Find Volume

$V = \pi r^2h$

$V = \frac{22}{7} * (21)^2 * 25$

By Cancellation,

$V = 22 * 3 * 21 * 25$

$V = 34650 cm^3$
