Question

the circumference of the base of cylinder is 180cm and its height is 30cm find its curved surface area

Answer 1

we know that circumference=2×pie× radius
then 180=2×22÷7×radius
then 180×7÷2×22=90×7÷22
=630÷22 which is the radius then curved surface area 2pierh
so 2×22÷7×630÷22×30
we will get the answer
