Question

Find the curved surface area of a right circular cylinder whose diameter of the base is 28 cm and

height is 15cm.​

Answer 1

A=2π d/2h+ 2π(d/2)^

=2•π•28/2•15+2•π•(28/2) ^

=2550.97323cm^

A=2550.97cm^

Answer 2

Step-by-step explanation:

Diameter =14 cm

Radius =7 cm

Height =15 cm

So,

TSA of cylinder =2πr(r+h)

›››› 2×22 × 7 (7+15)

7

›››› 2×22 × 7 × 22

7

= 968cm²

CSA of cylinder =2πrh

2×22 7 × 15

7

=660 cm²
