Answer:
If R = 1, ~12.57 is the y. (r is the x.)
If R = 2, ~50.27
If r = 3, ~113.1
If r = 4, ~201.06
Step-by-step explanation:
The formula of a cone is pi * r^2 * h/3
If r = 1, we have pi * 1^2 * 12/3
12/3 = 4
and 1^2 = 1
pi * 1 * 4
4 * pi = ~12.57
if r = 2, we have an imrpoved formula,
pi*2^2 * 4 (h/3 became 4 since 12/3 = 4)
2^2 = 4
4*4 = 16
pi * 16 = ~50.27
If r = 3
our formula is pi*3^2*4
3^2 = 9
pi*9*4
9*4 = 36
36* pi = ~113.1
If r = 4,
our formula is
pi*4^2*4
4^2 = 16 and 16*4 = 64
pi*64 = ~201.06.
