Question

Find the curved surface area, total surface area and volume of a cylinder with diameter 7cm and height 5 cm. π = (7/22)​

Answer 1

Step-by-step explanation:

C.S.A = 2πrh

T.S.A = 2πr(h+r)

VOLUME = πr²h

height = 5cm

radius = 7/2

C.S.A = 2×22/7×7/2×5

= 110cm²

T.S.A = 2×22/7×7/2×(5+7/2)

= 187cm²

volume = 22/7×7/2×7/2×5

= 192.5cm³
