Question

find th surface area of a cylinder of diameter 14cm and height 21cm

Answer 1

Answer:

curved surface area = 924cm²

Explanation:

Dimensions of a cylinder:

diameter (d) = 14cm

radius (r) = d/2 = 7 cm

height (h) = 21cm

Curved surface area of the

cylinder = 2πrh

= 2×(22/7)×21×7

= 2×22×21

= 924 square cm

Therefore,

curved surface area = 924cm²
