Diameter = 2 * radius So in this case, 40 feet.
40'
Well this depends on If the radius is 40 inches or If 40 inches is the entire diameter. Circumference is determined using the formula Pi x Radius² Assuming 40 is only a radius it would be 3.14 x 40² or 3.14 x 1600 = 5024 inches If 40 inches is the entire diameter then its simply Pi x Diameter since the entire diameter is the radius squared. 3.14 x 40 = 125.6 inches.
40 ft
Double the value of the radius which in this case is 2*20 = 40 feet
The radius is 1/2 of the diameter, so if the radius is 20 units then the diameter is 40 units. You multiply the radius by 2 to get the diameter.
Diameter = 1 BECAUSE diameter = 2 x radius
Diameter = 2 * radius So in this case, 40 feet.
the hole has a 20 foot diameter and a 10 foot radius
40'
1.593 and a half. hope that answers your question!

This cannot be properly answered because a 20 cm radius equates to a 40 cm diameter. Also, a 50 cm diameter means a 25 cm radius.
20 millimeters
40 ft
Double the value of the radius which in this case is 2*20 = 40 feet
Area of rod = length*diameter*pi
