Question

compute the curved surface area if a hemisphere whose diameter is 14 cm

Answer 1

For Hemisphere,

diameter d=14 cm
∴radius r=7 cm

Curved Surface Area = 2 π r²
                                   = 2 * 22/7 * 7²
                                   = 44 * 7
                                   = 308 cm²

Thus, Curved Surface Area of the Hemisphere is 308 cm²

Answer 2

curved surface area of a hemisphere = 2πr²
diameter = 14 cm
radius = 7cm
C.S.A of hemisphere = 2×22/7×7×7 = 308 cm²
