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.
solve it ithink
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.
You an use the formula for the area of a circle (A = pi x r2), insert the area, replace pi with 3.14 (this is an approximation), and solve for r.
The formula for the area of a circle is pi*r2. So since we have the area, plug this into the formula and solve for r: 7500 = pi*r2 r2 = 7500/pi = 2387.32 r = sqrt(2387.32) = 48.86 So your radius is approximately 48.86 ft.
The radius of the circle is 24.5010345. The area of a circle is given by the equation A = 2 * π * r where r is the radius of the circle. In our case, we already know the area. So we can substitute that in. 153.94 = 2 * π * r Now we solve for r. Divide both sides by 2π 153.94 / (2π) = r Approximately π as 3.1415... 153.94 / (2 * 3.1415) 153.94 / 6.283 r ~= 24.5010345
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 circumference is the perimeter of a circle. It is used often in mathematics to solve word problems in geometry.
abscissa = sqrt[1 - square of the ordinate]
The area of a circle is (pi)(r^2). Set this equal to 64 and solve for the radius. r = sqrt(64/pi)
