If the diameter of a circle is 20 inches what is the radius of the circle?

10 inches
The diameter of a circle is twice the radius, so 1/2 of 20 inches is 10 inches.
to make this sound easier: you just take half of the diameter.
for instance lets say the diameter was 5. so your thinking: how can you split a odd number in half but you just turn the diameter of 5 and turn the radius into 2.5.
u with me??
hoped i helped!! :) :)

If the radius of a circle is 10 inches what is the diameter?
The radius is half the diameter. The diameter is twice the radius. If the radius is 10 inches, the diameter is twice that, or 20 inches. The radius is any straight line that connects a point on the circle with it's center. The diameter is a line segment that connects two points on a cirle throught the center of the circle.Answer:Let r be the radius of the circle and d be the diameter of the circle. We know that the diameter = 2 * radius of the circle. Given the radius r = 10 inches. Diameter d = 2 * 10 Diameter = 20 inches.
If the radius of a circle is 20 what is the diameter?
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.

What is the diameter of a circle whose radius is 10?
20; the diameter of a circle is twice its radius.
What is the circumfernce of a circle 20 inches using 3.14?
Circumference of a circle = 2*pi*radius or pi*diameter
If a circles radius is 20 inches what is the circumference?
1256 inches ++ Another Answer ++ The formula for finding the Circumference of a circle is C = Pi x D where D is Diameter and Pi is 3.1416. The Radius of a circle is one-half of the Diameter, hence the Diameter of a circle with a 20-inch Radius is 40 inches. Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.
What is the radius of a 20 diameter circle?
The radius is 3.183
What is the radius of a 20cm circle?
That depends what you mean with "a 20 cm. circle". If 20 cm. is the radius, you already have the answer. If 20 cm. is the diameter, the radius is half the diameter. (10cm)
If the radius of a circle is 20 what is the diameter?
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.
What is the circumference of a circle if its diameter is 20 inches?
The circumference of a circle if its diameter is 20 inches is: 62.83 inches (diameter x Pi = circumference).
