Question

A hemispherical bowl is made of steel 0.25cm thick the inside radius of bowl is 5cm find the volume of steel making bowl.​

Answer 1

GIVEN :-

★ thickness = 0.25cm

★ inner or inside radius = 5cm

SOLUTION :-

→ outer volume = 2/3 π ( R³ ⁻ r³ )

→ 2/3*22/7 ( 5.25³ ⁻ 5³ )

→ 44/21 ( 144. 703125 - 125 )

→ 44/21 * 19.703125

→ 866.9375/21

→ 49.28cm³

Hence :-

• Volume of steel = 49.28cm³
