I DONT KNOW WHAT TO DO

Answer 1

ratio of surface areas is 1 to 4 or 4 to 1, depends on whether you want to write the bigger:smaller or smaller:bigger.

Answer 2

how?

Answer 3

let r(1) = 2(r2) then SA = 4pi(r)^2, input both and take the ratio

Answer 4

ohh:) soo sweet thank you

Answer 5

volume ratio is 1:8 or 8:1

Answer 6

ohh okay:)
