Find the volume of a hemisphere whose radius is 7 cm. (Given π = 22/7)
A hemisphere is one part of a sphere that is cut into two equal halves.
Answer: The volume of the hemisphere whose radius is 7 cm is 718. 6666 cubic cm.
Let's find the volume using the formula of volume of the hemisphere.
Explanation:
Given radius = 7 cm
We will use π = 22/7
Volume of a hemisphere = 2 / 3 π r3
⇒ (2 / 3 × 22 / 7 × 7 × 7 × 7) cm3
⇒ (2 / 3 × 22 × 7 × 7) cm3
⇒ (2,156 / 3) cm3
⇒ 718. 6666 cm3
You can use the volume of a hemisphere calculator to verify the answer.
Thus, the volume of the hemisphere whose radius is 7 cm is 718. 6666 cubic cm.
