The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.
Before we can set out in search of a solution,we need to know:What is the question ?What exactly does the 8,480 represent ?
Use the formula for the area of a circle (A = pi x radius2). Replace the data you know (the area), and solve for radius. Then, you can double this radius to get the diameter.
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.
Well, darling, if a circle has a circumference of 24 inches, we can use the formula C = 2πr to find the radius. Just plug in 24 for C and solve for r. You'll find that the radius of this sassy circle is 3.82 inches.
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.
In a circle
It depends on what information you have.
divide the radius by Pi2
pie (3.14) times Diameter
You cannot SOLVE a circle. You can find the radius of a circle, or its diameter, or circumference or area. Or you can find the equation of a circle in the Cartesian system or in polar coordinates. Or find other characteristics of the circle. In any case, a circle cannot have an area of 24 centemeter. Apart from the fact that there is no such word - try centimetre (or centimeter). A centimetre is a measure of length, not area.
You use the information you're given, along with the facts and formulas you know about the geometry of a circle.
The circumference of a circle is 2*pi*radius or diameter*pi
A wire 24cm long is cut into two, and one part is bent into the shape of a circle, and the other into the shape of a square. How should it be cut if the sum of the areas of the circle and the square is to be a minimum? I know the answer is (24pi)/(4+pi)cm for the circle and (96)/(4+pi)cm for the square but how to solve for it?
Radius of circle is the square root of 616/pi = 14m to nearest whole numberDiameter of circle is 2 times 14 = 28m
The area of a circle is (pi)(r^2). Set this equal to 64 and solve for the radius. r = sqrt(64/pi)
abscissa = sqrt[1 - square of the ordinate]
to find the circumference of a circle, which is the distance in the outside of the circle you need to use the following formula: C=dx 3.14 or circumference equals diameter times pi. The diamater is the length of the circle from end to end. Not very difficult.
