Question

If radius = 7 cm ,then find the volume of hemisphere ?​

Answer 1

The volume of the hemisphere is  718.66 cm³.

Step-by-step explanation:

The radius of the hemisphere, r = 7 cm

We know the formula of the volume of the hemisphere is given as,

Volume = $\frac{2}{3}$ × π × r³

Now, substituting the given values in the above formula

V = $\frac{2}{3}$ × $\frac{22}{7}$ × 7³

⇒ V = $\frac{2}{3}$ × 22 × 7 × 7

⇒ V = $\frac{2}{3}$ × 1078

⇒ V = 718.66 cm³ ← volume of hemisphere
