Capicity is measured in liters or milli liters.
Volume is 5266.47922 or 5266.48 cm³
∴ Capicity is 5.26648 litres .......(∵ 1 litre = 1000cm³)
Hope my answer help you.

Given External hollow hemispherical vessel r2 = 45.5cm. radius r = 22.75.
Capacity of hollow hemispherical vessel = 2/3 pir1^3
= 2/3 * 22/7 * (21)^3
= 2 * 22 * 21 * 21
= 19.404 litres.
Outer's surface area = 2pir2^2
= 2 * 22/7 * (22.75)^2 = 3253.25 cm^3.
