Question

Two cylinders have their radii in the ratio of 3:4 and their heights in the ratio 2:3. The ratio of their curved surface area is _______

Answer 1

Step-by-step explanation:

Explanation

We are given two cylinders that have their radii in the ratio 3:4

and heights in the ratio 2:3

Theory

The curved surface area of cylinder is given by

A = 2 pi *r*h

Procedure

Now we need to take the ratio of the surface areas

A1/A2 = R1/R2*H1/H2

the ratio is 1/2

3/4*2/3 = 1/2
