I think 12 percent but sorry if I got it super wrong
Formula for surface area of a sphere of radius r is A = 4pi*r^2.
The same formula, for the case where the radius is 2.45 times greater, comes out to A = 4pi*[2.45r]^2.
Just find the ratio of
4pi*r^2 to 4pi*[2.45r]^2. It is 1/6.
Answer:4
Step-by-step explanation:
It equals 3/16 because I first multiplied the first to fractions together and I know that negative times a positive is negative so we would get a negative and I also multiplied the 2 to get -9/40 and then multiplied -5/6 to -9/40 to get the answer of 3/16!
