How do you find a diameter of a circle?

If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)


Formula for finding radius of a circle?

c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.


How do you find area of a circle when you have the circumference circle?

Divide the circumference by pi, and that will give you the diameter. Then take half of the diameter (the radius), and plug it into the formula for the area of a circle (A=πr²)


If area of a circle is tripled what haappens to the circumference?

The formula for the area of a circle is, A = πr2 If the area is tripled then the larger circle has an area of A2 = πR2 (where R is the new radius) But, πR2 = 3πr2 : R2 = 3r2 : R = r√3 The circumference of the original circle was 2πr. The circumference of the larger circle is 2πR = 2πr√3 Therefore, if the area is tripled, then the circumference increases by √3.

If the area of a circle is 201.06 then the circumference of the circle is?

The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.

What is the formula for finding the radius?

The formula for finding the radius of a circle is circumference divided by double of pi. If area is given instead of circumference, the radius may be found by dividing the area by pi, then finding the square root of the resultant quotient. It is also equal to half of the diameter, or the diameter divided by 2.
