1.

Diameter of a hemispherical toy is 56 cm find its curved surface area, total surface area and volume.

Answer»

Diameter of hemisphere = 56 cm

Its radius = d/2 = 56/2

Radius = 28 cm

T. S. A of hemisphere = 3πr2

= 3 × 22/7 × 28 × 28

= 7392 cm2

C. S. A of hemisphere = 2πr2

= 2 × 22/7 × 28 × 28

= 4928 cm2

Volume of hemisphere = 2/3 πr2

= 2/3 × 22/7 × 28 × 28 × 28

= 45994.666 cm3
