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.
