Question

the radii of the circular ends of a frustum shaped bucket are 14 cm and 7 cm the height of the bucket is 45 cm find the capacity of the bucket ​

Answer 1

Answer:

R=14cm , r=7cm

h=45cm

capacity of the bucket = volume of frustum =

π/3*h* ( R^2 +r^2+R*r)

= π/3*45*(14^2 + 7^2 +14*7)

= π/3*45*(196+49+98)
