Answer:
Option 1. 255.4 cm³
Step-by-step explanation:
Since radius of the ball at the outer surface is = 5 cm³
Therefore volume of the ball formed by outer surface = (4/3)×π×5³ cm³
The ball is made up of 1 cm thick rubber so the radius of ball with inner surface = 5-1 = 4 cm
and volume of the ball formed by inner surface = (4/3)×π×4³ cm³
Now the volume of the rubber = Volume of the ball with outer layer - Volume of the ball with inner layer
V = (4/3)×π×5³ - (4/3)×π×4³ = (4/3)×π×(5³- 4³) = (4/3)×3.14×(61) = 255.38
V = 255.4 cm³
Option 1. 255.4 cm³ is the correct answer.
