Question

7. The ratio of the total surface area to the lateral surface area of a cylinder of base radius r
and height h is
​

Answer 1

Answer:h+r/h

Step-by-step explanation:

Hope it helps pls mark me as brainilest

Answer 2

Answer:

Since, there are two circles thus we get the total surface area of the cylinder given by 2πrh+2πr2 or Total surface area = 2πr(h+r). Hence, the required ratio of the respective areas is 4:3.
