Question

is the surface area of a sphere is 144 square CM then find its radius if the diameter of the sphere is doubled then find its volume​

Answer 1

Answer:

12738cm 3 9s th I will try again to get the

Answer 2

Answer:

Hey mate here is ur answer mark it as brainliest

Step-by-step explanation:

SA of sphere=4πr²

144cm² =4×π×r²

144π/4π =r²

36 =r²

√36=r

6 cm =r

So , d=12cm

When d is doubled 12×2=24 cm

r=12cm

Volume of sphere= 4/3πr³

=4/3×3.14×12×12×12

=7234.56cm³
