The radius of a circle is double its diameter. It would have a radius of 29/2, or 14.5 yards.
They are 4 points on the circle, and 29 on or in the circle.
Radius: 29/(2*3.14) = 4.618 rounded to 3 decimal places Area: 3.14*4.618 squared = 72.889 square m to 3 decimal places
Circumference of a circle = 2*pi*radius or diameter*pi
2 x pi x radius = circumfrance 2 x pi x radius = 29 29/ 2pi = radius radius = 4.62 (3 sig.fig.) 4 x pi x radius^2 = Surface area of sphere 12.56 x radius^2 = Surface area of sphere 12.56 x 4.62^2 = Surface area of sphere 268 cm2 (3 sig.fig)
The circumference of a circle if the radius is 29 is about 182.21
The radius of a circle is double its diameter. It would have a radius of 29/2, or 14.5 yards.
The formula for square footage of a circle uses the constant pi (roughly a value of 3.14) in its calculation and the length of the radius of the circle. Area of a circle equals radius x radius (R squared) x 3.14 (pi). If we are given that information that the circle is 29 wide (diameter), we know enough to find the answer. Since radius (R) equals 1/2 of diameter, divide 29/2=14.5 14.5 x 14.5 x 3.14= 660.18 square feet in a circle 29 feet in diameter.
area = π x radius2 radius = diameter/2 ⇒ area = π x (29/2)2 = 841π/4 ~= 660.5 cm2
They are 4 points on the circle, and 29 on or in the circle.

Since the formula for circumference is Pi (3.14) times the diameter, you can work it backwards to find the radius. You first divide the circumference, 29, by Pi (3.14), then divide it by 2 since the diameter, which you just found, is twice the radius. (In case you don't know, the diameter is the distance across the circle, and the diameter line passes through the center point. The radius is the distance from the center of the circle to the outside. Therefore, the radius is half of the diameter.) So, in this case, the radius of a circle with a circumference of 29 units would be approximately 4.6178 (rounded). Hope I made sense. :)
59 pi = 182.212 (rounded)
Radius = 1/2 (diameter) = 59/2 = 29.5 yards = 29 yards 1 foot 6 inches
Radius: 29/(2*3.14) = 4.618 rounded to 3 decimal places Area: 3.14*4.618 squared = 72.889 square m to 3 decimal places
Circumference of a circle = 2*pi*radius or diameter*pi
