Question

The surface area of two spheres are in the ratio 1 : 16, their radii are​

Answer 1

Answer:

r1:r2=1:4

Step-by-step explanation:

A1:A2=1:16 ------>r1:r2=1:4

Area of sphere=4¶r*2

A=r*2 then r=√(A)

Answer 2

${ \bold{area \: ratio = 1 \ratio16}} \\ { \bold{ \therefore \: radii \: ratio = 1 \sqrt{16} }} \\ { \bold{volume \: ratio = {1}^{3} \ratio (\sqrt{ {16} } {}^{2} }}) = { \bold{1 \ratio64 \: cm}}$
