Question

There is a beach ball with radius 24 cm and a ping pong ball with radius 4 cm. Find how many times greater the volume of the beach ball is as that of the ping pong ball.

A.) It is 128 times greater. B.) It is 36 times greater. C.) It is 216 times greater. D.) It is 6 times greater.

Please give the explanation and the answer as soon as possible!

Answer 1

Vbb = (4/3)pi(24)^3

Vppb = (4/3)pi(4^3)

dividing the volumes:

4/3 cancels

pi cancels

(24)^3/4^3 = (24/4)^3

24/4 = 6

6^3 = 216

C

Answer 2

V_bb = (4/3)π(24)³

V_pp = (4/3)π(4)³

(4/3)π(24)³ / (4/3)π(4)³

24³ / 4³

6³

216
