Question -

If the radii of the circular ends of a conical bucket which is 45 cm high be 28 cm and 7 cm, find the capacity of the bucket



Answer -

Given,

Height of the conicalbucket = 45 cm

Radii of the 2circular ends of the conical bucket are 28 cm and 7 cm

So, r1 =28 cm r2 = 7 cm

Volume of the conicalbucket = 1/3 π(r12 + r22 +r1 r2 )h

= 1/3 π(282 +72 + 28 × 7)45 = 15435π

Therefore, the volume/capacity of the bucket is 48510 cm3.
