Question

ona soild circular cylinder with height 10 cm and radius of the base 6 cm, a right circular cone of the same
height and same base is removed. Find the volume of the remaining solid. Also, find the whole surface area.​

Answer 1

Answer:

volume of cylinder = πr 2h

= 3.14x6^2 x 10=1130.40cm3

whole SA=2πr(r+h)

= 2x3.14x6 (6+10)

= 6.28x6x16 = 602.88cm2
