radius = 35/(2*pi) in cm
The formula to calculate the circumference of a circle is C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter of the circle. In this case, the diameter is 35 feet, so the circumference would be C = π(35) = 110.19 feet.
21
If 21 feet is the diameter, divide it by 2 to get the radius. Then use the formula for a circle: area = pi x radius2. 350 sq ft NOT the 35 the other people answered. A sheet of plywood 4' by 8' is 32 Sq ft thats a really small pool.
In order to find radians, you simply have to put Arc Length over Radius. Radius = 20 Arc Length = 45 45/20 = radians radians = 2.25
It is 35/2pi = 5.57 yards, approx.
A circle with a radius of 35 inches has a circumference of 219.91 inches.
radius = 35/(2*pi) in cm
Circumference of circle: 2*pi*35 = 220 cm rounded to the nearest whole number
Circumference of circle: 2*pi*35 = 220 m rounded to the nearest whole number
Circumference = 2*pi*rr = diameter/2 = 70/2 = 35 yards2*pi(35 yards)= 220 yards in circumference===================
70/2pi ie 35/pi = 11.14 ft
Presumably you mean "radius"... 70 pi sq mm
A 35-cm diameter circle has a circumference of: 110 cm
The circumference of a circle that has a diameter of 35 inches is 109.96 inches.
The diameter of a circle when the circumference is 35 cm is: 11.14 cm (circumference divided by Pi = diameter).
(Note: for typing purposes, pi will be represented as n) The formula for circumference is 2nr. First we need to find 'r' which stands for radius (the straight distance from the centre of the circle to the edge). Since the radius is half of the diameter, the radius is 70/2=35 yds. Now we can put 35 yds into the formula: 2*n*35 = 219.91 yds (rounded to 2 decimal places).
