Question

the circumference of the base of a cylinder is 132 cm and its height is 30 cm find the volume of the cylinder and its lateral surface area​

Answer 1

Step-by-step explanation:

circumference = (π × d) = 132

= (22/7) × d = 132

therefore d = 42 cm

volume of cylinder = (π/4) × (d^2) × h

= (22/7)×(1÷4)×(42^2)×30

= 41580 cm^3

lateral surface area = (π× d × h)

= (22/7)×42×30

=3960 cm^2
