Question

Find the ratio of surface area and volume of sphere of radius 1 unit

Answer 1

Answer:

3:1

Step-by-step explanation:

radius of the sphere is '1 unit'.

So. the surface area = 4π r^2  (r=1)

Volume = 4/3 π r^3 (r=1)

Ratio

= 4(1)(1) / 4/3(1)(1)(1)

= 1 / 1/3

= 3 / 1

So

3 : 1 is the ratio of the surface area and the volume of the sphere of unit length.
