Question

The perimeter of the base of the cylinder is 22 cm, if its height is 10cm, then its curved surface area in sq. cm is​

Answer 1

Answer:

220 cm2

Step-by-step explanation:

perimeter of base( perimeter of circle)= 22cm

formula of perimeter of circle= 2πr

2πr=22cm

2*π*r=22

so r=7/2cm

Height of cyclender=10cm

curved surface area of cyclender=2πrh

2* 22/7 *7/2 *10

=220cm^2
