Question

A right circular cylinder has base radius 14 cm and height 21 cm. Find curved surface area.​

Answer 1

Answer:

1848 cm2

Step-by-step explanation:

Given,

Radius r = 14 cm

Height h = 21 cm

Calculation,

Curved surface area of a right circular cylinder = 2πrh

= 2 × 22/7 × 14 × 21

= 1848 cm² Ans.

Ans.) The curved surface area of a right circular cylinder is 1848 cm².

Answer 2

Answer:

csa of right circular cylinder=616 cm^2

Step-by-step explanation:

radius =r=14 cm,height=h=21 cm

csa of right circular cylinder=2πrh

                                             =2*22/7*14*21

                                             =2*22*2*3

                                             =44*14

                                             =616 cm^2
