Question

1. Find the volume of a half sphere with radius equal to 6m
2.Find the volume of a wheel with radius equal to 50cm and width equal to 30cm

Answer 1

Hie!!

1) Half sphere means hemisphere.

Volume of hemisphere = 2/3 ( πr³ )

Where r is radius.

Here = 6m

So, it's volume is = 2/3( π × (6)³ )

= 452.16m³

2) Volume of wheel = π r² h

Where r is radius and h is width

here r = 50cm and h = 30cm

So, Volume = 3.14 × (50)² × 30

= 235500cm³
