Circumference of a circle = 2*pi*radius or diameter*pi
The formula is: A = PI(r)^2 A circle with a radius of 29 cm has an area of 2,642.08 square cm.
29 inches
91.06
They are 4 points on the circle, and 29 on or in the circle.
Radius = 1/2 (diameter) = 59/2 = 29.5 yards = 29 yards 1 foot 6 inches
29 cm
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.
Circumference of a circle = 2*pi*radius or diameter*pi
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. :)
You take the radius of 29 centimeters and double it for the diameter - 58 centimeters.Then you could multiply the diameter of 58 centimeters by pi, which is 3.141 (approximately).This would give you the circumference of 182.178 centimeters.
The circumference of a circle if the radius is 29 is about 182.21
area = π x radius2 radius = diameter/2 ⇒ area = π x (29/2)2 = 841π/4 ~= 660.5 cm2
The diameter of a circle with a circumference of 29 feet is about: 9.231 feet.
The circumference of a circle = 2πr or πd where r is the radius and d is the diameter.Therefore, 29 = πd : d = 29/π = 9.230987 feet (6dp).NOTE : As π is an irrational number then an exact value cannot be given to it. The answer is therefore an approximation of the diameter. It is not an exact length.
