Question

The ratio of the volume and surface area of a
sphere of unit radius numerically is
(1) 4:3
(2) 3:4
(3) 1:3
(4) 3:1​

Answer 1

Answer:

May be the answer of this question is 1:3.

Hope it's helpful to you.

According to my point of view this is the correct answer.

Answer 2

Answer:

1:3

Step-by-step explanation:

unit radius,r=1

volume of sphere=4π(1)^3/3

=4π/3

Surface area of sphere= 4π(1)^2

=4π

volume of sphere:surface area of sphere

(4π/3)÷4π

(4π/3)×1/4π

1/3

1:3
