Question

Find the total surface area of a solid hemisphere of radius 10 cm. [Use $\pi =3.14$]

Answer 1

Given that,

The radius of a solid hemisphere is $10cm$.

To find out,

The total surface area of the hemisphere.

We know that, total surface area of a solid hemisphere $=3\pi r^2$

Here, $r=10cm,\pi =3.14$

Hence, total surface area $=3\times 3.14\times (10{)}^2$

$=942c{m}^2$

Hence, the total surface area of the given hemisphere is $942c{m}^2$.
