Question

The diameter of a hemispherical bowl is 14 cm .its curved surface area will be equal to ​

Answer 1

Given :-

Diameter of a hemispherical bowl => 14 cm

Radius of a hemispherical bowl => 7 cm

To Find :-

Curved surface area :-

Formula Used Here :-

Curved surface area of hemisphere => 2πr²

Solution Start :-

$Curved \: surface \: area \: of \: hemisphere \: = > 2\pi {r}^{2} \\ \\ Curved \: surface \: area \: of \: hemisphere \: = > 2 \times \frac{22}{7} \times 7 \times 7 \\ \\ Curved \: surface \: area \: of \: hemisphere \: = > \frac{44}{\cancel {7}} \times \cancel {7} \times 7 \\ \\ Curved \: surface \: area \: of \: hemisphere \: = > 44 \times 7 \\ \\ Curved \: surface \: area \: of \: hemisphere \: = > 308 \: {cm}^{2}$

Hence, Curved Surface Area => 308 cm²
