Question

13. A tennis ball is of diameter 70 cm. What is its
volume in (a) cm^3 (b) m^3?
[(a) 179.6 cm^3 (b) 0.0001796 m^3]​

Answer 1

$\huge\underline\bold {Answer:}$

Option a

Given,

Diameter of the ball = 70 cm

Volume of the ball = 4/3 π r^3

Since, diameter is 70 cm then radius will be 70/2

= 35 cm.

Therefore, Volume = 4/3 π × 35

= 4/3 × 22/7 × 35

= 440/3 cube centimetre.
