If the diameter of a sphere is 7 cm, then find the volume of the sphere. (use $\pi =\frac{22}{7}$ ) (Rounded up to two places of decimal).

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 179.67 cm³.

Radius (r) = 7/2 = 3.5 cm

Volume (V) = (4/3)πr³

= (4/3) × (22/7) × (3.5)³

= 179.666...

≈ 179.67 cm³

Therefore, the volume of the sphere is approximately 179.67 cm³.
