The diameters of two circular ends of a bucket are 44 cm and 24 cm and the height of the bucket is 35 cm . The capacity of the bucket is

Options

A. 31.7 litres
B. 32.7 litres
C. 33.7 litres
D. 34.7 litres

Answer

B

Explanation

Here R=22 cm ,r = 12 cm and h = 35 cm
Capacity of the bucket `=1/3 pi h(R^2 +r^2 +Rr)cm^3`
`=1/3 xx 22/7 xx35xx[(22)^2 +(12)^2 +22 xx 12] cm^3`
`=((11)/(3)xx 892 )cm^3 =(110xx 892)/(3xx 1000)` litres = 32.7 litres.
