Detailed Solution

Given that, the radius of the hemisphere is 6.3 cm.
The formula for the volume of hemisphere is given by,
Volume of a hemisphere

= \frac{2}{3} π r^{3}

.
So, after substituting the value of all the dimensions in the formula we get,

⇒ 23 × 227 × (6.3) 3 ⇒ 2 × 22 × 2.1 × 0.9 × 6.3 ⇒ 523.9 c m 3

Therefore, the volume of a hemisphere of radius

6.3 cm

523.9 c m^{3} .

Hence option (1) is correct.
