Question

Find the volume of the hemisphere.

Answer 1

THE FORMULAE OF HEMISPHERE : V = 2/3 * π * r³

Explanation:

Put the formulae of hemisphere,

V = 2/3 * π * r³

Put the values in the formulae,

= 2/3 × 3.14 × 9³

= 0.6666 × 3.14 × 729

= 2.09312× 729

= 1525.8m³ ans

→ value of π (pie) is 3.14

→ formulae of radius is d/2 = 18/2 = 9 in
