What is the radius of a circle if the circumference is 6 inches?
Circumference is equal to 2(pi)r. So if C = 6, and 2(3.14)r = C, then solve for r r= 6/2(3.14) = .955
How do you solve v equal pi r square h solve for h?
V = pi*(r^2)*h is the formula for the volume of a cylinder. In order to solve for 'h' (or the height), do the following:V = pi*(r^2)*h --> divide both sides of the equation by pi*(r^2) to get rid of pi*(r^2) on the right side of the equation.V/(pi*(r^2)) = (pi*(r^2)*h)/(pi*(r^2)) --> cancel out the common term (pi*(r^2)) in the right side of the equation.You are left with the original equation in terms of 'h':h = V/(pi*(r^2))
What is the radius of a circle if the area is 64?
The area of a circle is (pi)(r^2). Set this equal to 64 and solve for the radius. r = sqrt(64/pi)
What is the radius of a circle that has the same area and circumference?
Circumference, C = 2*Pi*R Area, A = Pi * R^2 A = C Pi * R^2 = 2*Pi*R --> solve for R (radius) R = 2 So, the radius of a circle with area = circumference is two.
A circle has a circumference of 16 pi inches what is its radius?
The formula where C=circumference, R=radius is C = 2 pi R Since C = 16 pi inches and 16 pi = 2 pi R we can solve for R and get R= 16 pi /2 pi = 8 Therefore the Radius is 8 inches.
