Answer:
The diameter of a tennis ball = 7 cm
Radius of the tennis ball = 7/2cm
SOLUTION:
The ball is in the shape of a sphere. So, we should find the volume of sphere.
We know that,
Volume of Sphere = 4/3πr²
4/3 × 22/7 × 7/2 × 7/2 × 7/2
==> 1/3 × 11 × 7 × 7 ×
==> 11 × 49 × 1/3
==> 539/3
==> 179.66 cm³
Convert 179.66cm³ into m³
179.66 * 10^-6 m = 0.00017966m³
Therefore, the volume of ball is 179.66cm³.
