I think the answer would be 4/5
To find it directly
A = 2 pi r h
A is proportional to rh
factor 2
A is multiplied by 2 * 2 = 4
factor 3
3 * 3 =9
factor 5
5 * 5 = 25
factor 10
10 * 10 = 100
(b) the increase in A by factor x is x^2
c(20)^2 = 400
Answer:
A= 201.06
Step-by-step explanation:
A=πr^2
d=2r
Input the information into those formulas. Im honestly not sure if thats the right answer but its better than nothing.
