Question

The volume of a hemisphere is
5749.33 cm3. Find its diameter
(in cm).​

Answer 1

$\mathcal \red{SOL:-}$

volume of hemisphere = 2π³/3

5749.33 = 2π r³/3

5749.33×3 = 2π r³

17247.99 = 2π r³

17247.99/2 = π r³

8623.995 = 22/7 r³

8623.995 × 7/22 = r³

2743.99 = r³

13.99 = r

2r = diameter

2 × 13.99 = d

d = 27.98 cm
