Answer :

Volume of HEMISPHERE is 718.6cm³

Given :

Diameter is 14cm

To find :

Volume of a hemisphere

Solution :

Given Diameter is 14cm

Radius = 14/2 = 7cm
Radius is 7cm

As we know that ,

Volume of hemisphere = 2/3 πR³

where r is 7cm

⟶ V = 2/3 × 22/7 × 7³

⟶ v = 2/3 × 22/7 × 7 × 7 × 7

⟶ v = 2/3 × 22/7 × 343

⟶ v = 718.6cm³

Hence , Volume of hemisphere is 718.6cm³

More EXPLANATION :

Volume of hemisphere = 2/3 πr³
surface AREA of hemisphere = 2πr²
