2r = 7
r = 7/2
curved surface area of cylinder is = perimeter of circle × height.
= 2πrh
=2 × 22/7 × 7/2 × 10

the base of cylinder is a circle
therefore,
perimeter of a circle is 2πr
so,
Step-by-step explanation:
2*22/7*r=22
2r=22*22/7. =7
r=7/2
curved surface area of a cylinder=perimeter of circle*height
ie
2πrh
ie
2*22/7*7/2*10
=220 cm²(unit)
