A circle has radius r what is the formula for the area of the circle?
For a circle or radius r, the area is given by: area = {pi}r2 (ie pi times the radius squared)
What is the radius of a circle with an area of 32.1 square feet?
To find the radius of a circle given its area, you can use the formula for the area of a circle, A = πr². Rearranging this formula to solve for the radius gives r = √(A/π). Substituting the given area (32.1 square feet) into the formula, the radius is r ≈ √(32.1/π) ≈ 3.19 feet.
How do you find the radius of a circle when the area is given?
-- Take the formula for the area of the circle in terms of the radius . . . A = (pi) R2-- Solve that formula for 'R'. You'll then have a formula for the radius in terms of the area,which is exactly what you're looking for.
Radious formula for a cicrle?
It is not clear whether you want the formula of some aspect (area or circumference) of a circle when given its radius or a formula for its radius when given some characteristic measure of the circle.
What is the formula for area of the circle?
The formula for area of a circle is TTr2.This means that we multiply 3.14(the rounded off nunber for pi) by the radius and radius(3.14xradiusxradius).If the diameter is given,divide it by 2 to get the radius.
If the area is 628 what is the radius of a circle?
To find the radius of a circle with a given area of 628, you can use the formula for the area of a circle, A = πr^2, where A is the area and r is the radius. Rearranging the formula to solve for the radius, you get r = √(A/π). Substituting the given area of 628 into the formula, you get r = √(628/π) ≈ √(199.87) ≈ 14.14. Therefore, the radius of the circle is approximately 14.14 units.
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.
What is the formula to find the area of a circle with the radius given?
A = pi x radius squared where pi = 3.14
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 area of a circle with a radius of 21 feet?
Using 3.14 as Pi the area of circle is: 1384.74
What is the formula to find the radius given the are of a circle?
it is square root of the area divided by pi
What is the radius of a circle if the area is 153.86cm2?
To find the radius of a circle when given the area, you can use the formula A = πr^2, where A is the area and r is the radius. Given that the area is 153.86 cm^2, you can plug this value into the formula and solve for r. 153.86 = πr^2 r^2 = 153.86 / π r = √(153.86 / π) ≈ √49 ≈ 7 cm Therefore, the radius of the circle is approximately 7 cm.
