Find the total surface area of a hemisphere and a solid hemisphere each of radius 10 cm. (Use π = 3.14)
We have,
Radius = 10 cm
Total surface area of a hemisphere = 2πr2
⇒ Total surface area of a hemisphere = 2 × 3.14 × 10 × 10 = 628 cm2
Total surface area of a solid hemisphere = 3πr2
⇒ Total surface area of a solid hemisphere = 3 × 3.14 × 10 × 10 = 942 cm2
