The ratio of the curved surface area of the cylinder to
the that of sphere.

Best answer with explanation will be mark as brainliest​

Answer 1

Answer:

The ratio is equal to 2:3 or in fraction, it will be equal to 2/3.

Step-by-step explanation:

According to the question,

Vol. of sphere = Vol. of cylinder

i.e, 4/πr^3 = πr^2h

=> 4/3r = h

Curved surface area of cylinder ÷ Surface area of sphere i.e, 2πrh ÷ 4πr^2

= 2/4 × h/r

= 2/4 × 4/3

= 2/3 or

In ratio, 2:3
