Circumference of a circle = 2π r (2 * π * radius) or πd (π * diameter)
Hello from MrBillDoesMath
Answer:
See below for steps.
Discussion:
As I understand the problem statement we have a cylinder of height h and radius r. The volume of the cylinder is given by the formaul:
V = (pi * r^2) h
Divide both sides by (pi * r^2):
V\ (pi * r^2)) = ( (pi * r^2) * h ) \ ((pi * r^2) =>
V\ (pi * r^2) = 1 * h = h as (pi * r^2) \ (pi * r^2))
Therefore, h = V\ (pi * r^2)
Thank you,
Mr. B
Think of sea level as 0 on number line
-13 + 6 - 15
The radius is 2 and area = r^2*pi so 4*pi gives you 12.56 so the exact answer would be 12.56 and the answer with pi would be 4 times 3.14!
