Question
The volume of a hemisphere is 2425 (1/ 2) cm3
. Find its radius (Take p = 22/7)Solution
Let the radius of the hemisphere be R (2/3) x (22/7) × R3 = 2425.5 (2/3) × (22/7) x R³ = (4851/2) (2/3) × (22/7) × R³ = (99 × 49)/2 R³ = (3 × 3 × 11 × 7 × 7 × 3 × 7)/ (2 × 2 × 2 × 11) R³ = (3 × 3 × 3 × 7 × 7 × 7)/ (2 × 2 × 2) R = (3 × 7)/2 R = 10.5 cm. The radius of the hemisphere is 10.5 cm
