Area equals pi times the radius squared, so:
A=3.14x52
A=3.14x25
A=78.5 square yds.
pi x square of radius gives area. 3.14 x 100 = 314 sqft.
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
pi is a constant = 3.141592654 . . . . circle area = pi * ( ( diameter/2 )2 )
Area = pi*(diameter/2)2 = pi*252 = 1963.50 mm2
Diameter:6 radius:3 circumference:6(pi) area:9(pi)
Diameter = 314/pi feet
If 20cm is the diameter then radius is 10cm and area = Pi * r2 = Pi * 100 = 314 to the nearest square centimetre.
To find the diameter of a circle with a given area, you first need to calculate the radius using the formula for the area of a circle: A = πr^2. Given that the area is 314 cm^2, you can rearrange the formula to solve for the radius, which would be √(A/π). Plugging in the area, you get √(314/π) ≈ 10 cm. Finally, to find the diameter, you double the radius, resulting in a diameter of approximately 20 cm.
If Area of a circle = (2)(pi)(r), and diameter = 2r, then: diameter = 2r = Area of circle / pi, where pi = 3.14
pi x square of radius gives area. 3.14 x 100 = 314 sqft.
(12 x "pi" x 20) + 2(36 x "pi") which equals 314 x "pi" which equals about 985.96 when pi is 3.14
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
area = pi x diameter squared/4 = 400 pi diameter squared = 4 x 400 x pi/pi = 1600 diameter = sqrt 1600 = 40
pi*radius2 = area of a circle radius2 = area/pi radius = square root of (area/pi) diameter = 2*radius
area/pi = diameter 200.96/pi = 63.96755473 or 64 units in length.
