What is formula to find diameter of circle when area is known?
(Pi)r^2=area & 2r=d
Find the area and perimeter of a given circle?
If 'R' is the radius of the circle, then-- area of the circle is [ pi R2]-- perimeter of the circle is [ 2 pi R ]
How do you find area of a quadrant circle?
If the radius of the circle is r, then the area of the quadrant is 0.25*pi*r^2
How do you find the radius of a circle if you no the area?
You know: Area = (pi)r2 So, plug in your known values for the area and pi, then solve for r.
Area of a circle is 36 square centimeters what is the circumference of the circle?
The area of a circle with radius r is pi*r*r and its circumference is 2*pi*r Use the first to find r and then use that value of r in the second to find the circumference.
Formula to find area of circle?
The area of a circle can be found with the formula (pi)r^2
How do find the radius of a circle by the area?
r = +sqrt(Area/pi)
How do you find the radius of a circle if you have area?
The area of a circle is pi * r2 where r is the radius Solving for r, where A is the area: A = pi * r2 A/pi = r2 r = sqrt(A/pi)
Equation to find the area of a circle?
Area of a circle = (pi) (R2)R = radius of the circle = 1/2 of its diameter
What is the formula for finding an area of a circle?
The area of a circle with a known radius can calculated using the following formula where r is the radius : A = Pi(r)2
How can you find the diameter of a circle when the area is known?
Use the area formula for a circle. A = pi r squared. r is the radius, so solve for r and multiply by two to find the diameter. Need more help? Substitute the area for A, and 3.14 for pi in the previous equation. So to find the diameter, Divide area by 3.14 then find the square root of that and multiply by two.So Diameter = 2*Square_root(Area/pi)
How do you find the area of circle when its half of the circle?
Find the area of the whole circle and divide by two. Area of semicircle = 0.5*pi*r2, where pi = 3.14159 and r is the radius
