Question

Find the volume and curved surface
awa of a cylinder which is 140 cm high
has a base diameter of 10.5cm.​

Answer 1

Answer:

volume=12127.5 cm³ and c.s.a.= 4620 cm²

Step-by-step explanation: given r = 10.5/2 and h = 140 cm

Volume of cylinder = πr²h

                                 = 22/7 × 10.5/2 × 10.5/2 × 140

                                 = 12127.5 cm³

C.S.A of cylinder = 2πrh

                             = 2 × 22/7 × 10.5/2 × 140

                             = 4620 cm²
