If diameter of a cylinder is 2 inches what is the diameter?
2 inches
How many inches are a diameter?
The inches in a diameter = 2 X inches in the radius. Or, inches in a diameter = inches in circumference / pi

What is the radius in inches of a circle if the diameter is 3 inches?
Radius is merely..., diameter/2 3 inches/2 = 1.5 inches in radius ==============
How do you find the diameter and radius of a circle with a circumference of 2 inches?
Circumference = pi*diameter 2 = pi*diameter Divide both sides of the equation by pi: 2/pi = diameter diameter = 0.6366197724 inches radius is half of the diameter: radius = 0.3183098862 inches
Whats is the diameter if the circumference is 2 inches?
What is the diameter if the circumference is 2 inches? C = pi times d Diameter d = C / pi = 2 iches / 3.14156 = 0.63662 inches

Diameter = 8 inches.Radius = 1/2 of the diameter = 8/2 = 4 inches.
How do you convert the diameter of a circle to square Inches?
If you want the area of a circle, and you know the diameter, then: A = pi*r^2, where r is the radius, and is 1/2 the diameter, so pi*(diameter/2)^2 = (pi/4)*(diameter)^2. If you want square inches, then make sure you have the diameter measurement in inches, first.
