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.
Area = pi*(diameter/2)2 = pi*252 = 1963.50 mm2
pi is a constant = 3.141592654 . . . . circle area = pi * ( ( diameter/2 )2 )
Diameter:6 radius:3 circumference:6(pi) area:9(pi)
Diameter = 314/pi feet
Using pi as 3.14 it works out that the diameter is 20 cm
If 20cm is the diameter then radius is 10cm and area = Pi * r2 = Pi * 100 = 314 to the nearest square centimetre.
100*pi≈314 feet
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
If Area of a circle = (2)(pi)(r), and diameter = 2r, then: diameter = 2r = Area of circle / pi, where pi = 3.14
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
diameter = 2 Pi R = 6 ft so R=diameter/(2 pi) area = Pi R² = Pi x diameter²/(2² pi²)=6²/(4 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)
Area = (pi/4) x (Diameter)2 Diameter = 2 x sqrt(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.
