Question

.A hemispherical tank is made up of an iron sheet 1 cm thick. If the inner radius is 1 m, then find the volume of the iron used to make the tank.​

Answer 1

Answer:

$\frac{2}{3}$ π cm³

Step-by-step explanation:

volume of hemisphere is \frac{2}{3}πr³

putting r= 1cm,

then: $\frac{2}{3}$ × π ×(1)³

= $\frac{2}{3}$ × π × 1

= $\frac{2}{3}$ × π

= $\frac{2}{3}$ π cm³

=====================================

∴ Volume of required iron is $\frac{2}{3}$ π cm³.
