If a circumference of a circle is 28.26 inches what is the radius of the circle?

Well, isn't that a happy little question! To find the radius of a circle when you know the circumference, you can use the formula: circumference = 2πr. So, if the circumference is 28.26 inches, you can plug that in and solve for the radius. Just divide the circumference by 2π (which is about 6.28) to find the radius. Happy calculating!

What is the circumference of a 27 acre circle?

To find the circumference of a circle with a given area, you first need to calculate the radius. Since the area of the circle is 27 acres, you can use the formula A = πr^2 to solve for the radius. Once you have the radius, you can then find the circumference using the formula C = 2πr. By substituting the radius into the formula, you can calculate the circumference of the 27 acre circle.

How do find the circumference of a circle if you have the radius?

easy you just double it. Additional answer No, that's incorrect. If you double the radius you get the diameter. To get the circumference you multiply the radius by 2 then by 3.142. 3.142 is known as pi

How do you find circumference given radius?

2 pi rthis is the equation of the circumference of a circle. just multiply out 2 times pi(3.14159) times the radius that you were given.

How do you determine the circumference of a circle if you know the radius?

use the formula pi*diameter = circumference and the formula diameter = 2*radius and combine them 2pi*radius = circumference now you have a formula that you can just plug you numbers into. if you have 3 as your radius, then this is how to find the circumference 2pi*3=circumference 6.28*3=circumference 18.84=circumference
