Question

i) What will be the ratio of the surface area and volume of a sphere ?
(a) 3:r
(b) 2:r
(c) 3:4
(d) r: 3​

Answer 1

Answer:

tsa/vol= 4π$r^{2}$/4/3*π$r^{3}$ = a)3:r

Step-by-step explanation:

Answer 2

Step-by-step explanation:

TSA of sphere is 4πr²

volume of sphere is 4/3πr³

If we will divide them the we will get 3/r .

So ans is 3:r

option (a) is correct .
