Find the total surface area of a hemisphere of radius 10 cm. (Use π = 3.14)
Given,
Radius of the hemisphere (r) = 10 cm
By formula,
Total Surface area of hemisphere (A) = 3πr2
Substituting values we get :
A=3×3.14×(10)2=3×3.14×100=942 cm2.A = 3 \times 3.14 \times (10)^2 \\[1em] = 3 \times 3.14 \times 100 \\[1em] = 942 \text{ cm}^2.A=3×3.14×(10)2=3×3.14×100=942 cm2.
Hence, the total surface area of the hemisphere is 942 cm2.
