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.
What is the area of a circle if the radius is 7 mm?
The formula for an area of a circle is the greek symbol "pi" times the radius squared. A = π * r2 r = radius π = 3.14 Now, your radius is given to you in millimeters. Generally answers are given in meters. 7 mm (millimeters) is equal to .007 m (meters).
Area of a circle with 4 inch radius?
The formula to calculate the area of a circle is A = πr^2, where A is the area and r is the radius. Given a radius of 4 inches, we can substitute r = 4 into the formula to find the area. Therefore, the area of a circle with a 4-inch radius is A = π(4)^2 = 16π square inches, or approximately 50.27 square inches.
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.
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.
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.

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 formula to find the area of a circle with the radius given?
A = pi x radius squared where pi = 3.14
If the area is 628 what is the radius of a circle?
Well, let's think about this in a calm and peaceful way. To find the radius of a circle when you know the area, you can use the formula A = πr^2, where A is the area and r is the radius. In this case, if the area is 628, you can plug that into the formula and solve for the radius. Just take your time, enjoy the process, and you'll find the answer in no time.
What is the formula to find a area of a circle when given radius?
A = pi x radius2
What is the formula to be used if the diameter is given?
The answer depends on the formula for what: the radius, circumference, length of an arc, area, area of sector, area of segment: each one has a different formula.
What is the formula in finding the height of a cylinder?
The answer depends on what information you are given: volume and radius or diameter, or surface area and radius, etc.
