Question

the ratio of volume and CSA of cylinder is 7:2 find the radius of cylinder​

Answer 1

Answer:

Radius of cylinder is 7 units.

Step-by-step explanation:

According to info from the question, we can say that π r² H / 2πrh = 7/2

⇒ π x r x H / 2 x π x r x H = 7 / 2

cancelling out the  1 r from numerator and denominator, the H and π, we are left with

r/2 = 7 / 2

cross multiplying , we get

r = 14/2

∴ r = 7 units.
