Find the ratio of the surface area of the small cylinder to the surface area of the large cylinder.
Answer to Problem 3CYU
4:25
Explanation of Solution
Given:
Two similar cylinders have radii of 15 inches and 6 inches .
Formula Used:
Two
The Surface area of a cylinder is :
Calculation:
Given:
Since the two cylinders are similar , the ratio of their corresponding linear measures are equal:
So,
The ratio of the surface area of the smaller cylinder to the larger cylinder is :
So, the ratio of the surface area of the small cylinder to the surface area of the large cylinder is 4:25.
