Question

volumes of two spheres are in the ratio 64:27 then find the ratio of their surface areas​

Answer 1

hola♥️

volume of sphere=4/3πr³

ratio=r³/R³=64/27

r/R=4/3

surface area=4πr²

r²/R²=16/9

hope it helps ♥️

Answer 2

Answer:

look put the formula

Step-by-step explanation:

starting at volume of sphere is basically πr3 so by that

u will get

πr3=πR3

\π cancel out

so u will get.

r3=R3

put down ratio

64:27

cube root it

4:3

that's it

that's your answer
