Question

images of spear is twice the radius of another sphere then find the ratio of the volume​

Answer 1

HERE IS UR ANSWER ❤️

Radius of sphere A= 2r

radius of sphere B= r

now ratio of volume of spheres= 4/3πr3=4/3πr3

=r3=r3

=8r3=r3

=8:1

now,

ratio of area of spheres=4πr2=4πr2

=4r2=r2

=4:1

I hope u understand
