Question
A hemi-spherical bowl has negligible thickness and the length of its circumference is 198 cm. Find the capacity of the bowl.

Solution
Let r be the radius of the bowl.
∴ 2πr = 198
`=> r = (198 xx 7)/(2 xx 22)`
`=>` r = 31.5 cm
Capacity of the bowl
= `2/3pir^3`
= `2/3 xx 22/7 xx (31.5)^3`
= 65488.5 cm3
