The diameter of a circle is twice length of a radius, because it is basically two radii (plural of radius) joined together so they form a continuous line across the circle. If you multiply the length of the radius, 40 meters, by 2, then you get the length of the diameter, 80 meters.

How many Inches is diameter if radius is 9 yards?
The diameter is twice the radius in inches: 18*36 = 648 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
How many square feet in a circle that is 3 feet in diameter?
diameter is 3 ft diameter = 2*radius diameter/2 = radius 3/2 = 1.5 ft = radius area is pi * radius2 3.14 * (1.5)2 3.14 * 2.25 = 7.065 sq ft
