Square the radius and multiply the result by 3.14. You may want additional digits of pi for greater precision, but that's the basic idea.
The formula is πr² (that's "pi r squared," if the character doesn't show up properly).
ANSWER:The above answer is wrong! The above gives the area of a circle, not the circumference. Besides pie are round, cornbread are square.Pi = 3.1416 as stated above.
The circumference of a circle is 2 times the radius times pi .
This is because pi for all circles is the circumference divided by the diameter. So, pi times the diameter equals the circumference. The diameter is twice the radius.

The radius of the circle is 5inches what is the circumference?
The circumference of a circle that has a radius of 5 inches is 10 X pi or approximatly 31.415926535897932384626433832795. If you know the radius you can find the circumference by multiplying it by 2(pi)
If the circumference of the circle is 75.36 what is the radius?
To find the radius of a circle when given the circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 75.36, you can plug this value into the formula and solve for the radius. First, divide the circumference by 2π to find the radius. The radius of the circle would be 75.36 / (2 * 3.14159) ≈ 12. The radius of the circle is approximately 12 units.
How do you find out the circumference of a circle?
Circumference = 2*pi*radius or diameter*pi
