Question

Find the total surface area of a hemisphere of radius 10 cm. (Use t = 3.14)​

Answer 1

Area = 942 cm²

Step-by-step explanation:

• Radius = 10 cm

$= > \bf \color{red}{surface \: area = 3 \times \pi \times {r}^{2} } \\ = > 3 \times 3.14 \times {(10)}^{2} \\ = > 3 \times 3.14 \times 100 \\ = > \boxed{942 \: {cm}^{2} }$
