Question

If the total surface area of hemisphere is27cm2 then find its radius

Answer 1

Step-by-step explanation:

The total surface area of a hemisphere

$The \: total \: surface \: area \\ \: of \: a \: hemisphere \: = \: 3\pi {r}^{2} \\ \\ tsa \: of \: the \: \: hemisphere \\ = 27 {cm}^{2} \\ = > 3\pi {r}^{2} = 27 {cm}^{2} \\ {r}^{2} = 27 \div 3 \div \pi \\ = > {r}^{2} = 2.863 \\ r = 1.692 \: cm$

Answer 2

The Required Solution is

Radius of the Hemisphere = 1.692 cm
