Area equals pi times the radius squared, so:
A=3.14x52
A=3.14x25
A=78.5 square yds.

What is the square footage of a 20 ft diameter circle?
pi x square of radius gives area. 3.14 x 100 = 314 sqft.
What is the diameter circumference and area of a circle with a diameter of 8?
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
What is the area of a circle if it has a diameter of 50mm?
Area = pi*(diameter/2)2 = pi*252 = 1963.50 mm2
What is the format to calculate the area of a diameter?
pi is a constant = 3.141592654 . . . . circle area = pi * ( ( diameter/2 )2 )
What is the diameter radius circumference and area of a circle with a diameter of 6?
Diameter:6 radius:3 circumference:6(pi) area:9(pi)
What is the diameter of a circle if the circumference 314 feet?
Diameter = 314/pi feet
What is the diameter of a circle whose area is 314 cm square?
Using pi as 3.14 it works out that the diameter is 20 cm
What is the area of a 20 cm cercle to the nearest cm-squared?
If 20cm is the diameter then radius is 10cm and area = Pi * r2 = Pi * 100 = 314 to the nearest square centimetre.
Circumference of a circle with a diameter of 100 feet?
100*pi≈314 feet
What is the square footage of a 20 ft diameter circle?
pi x square of radius gives area. 3.14 x 100 = 314 sqft.
What is the formula for finding the diameter with the area?
If Area of a circle = (2)(pi)(r), and diameter = 2r, then: diameter = 2r = Area of circle / pi, where pi = 3.14
What is the Surface Area of a cylinder with diameter of 12 cm and a height of 20 cm?
(12 x "pi" x 20) + 2(36 x "pi") which equals 314 x "pi" which equals about 985.96 when pi is 3.14
What is the diameter circumference and area of a circle with a diameter of 8?
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
What is the area of a circle whose diameter is 6 feet?
diameter = 2 Pi R = 6 ft so R=diameter/(2 pi) area = Pi R² = Pi x diameter²/(2² pi²)=6²/(4 pi)
How do you find a diameter of a circle?
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)
What is the relationship between the diameter and area of a circle?
Area = (pi/4) x (Diameter)2 Diameter = 2 x sqrt(Area/pi)
What is the diameter of a circle that is equal to 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.
