Answer:
Step-by-step explanation:
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:
v
Step-by-step explanation:
If n is the number of cans in row r
n = 9 - r where r is a natural number less than 9
When r = 5 then n = 9 - 5 = 4
(you could let r = 9 as the ninth row has zero cans but values above 9 will give negative counts)
