A radius is not part of pi.
radius = sq rt of (2122.64/pi) = 25.99340872 or about 26 units of measurement
Using 3.14 as Pi the area of circle is: 530.66
Area of a circle: pi times radius squared
2*pi*radius = circumference 2*pi*radius = 13 Making the radius the subject of the formula is: radius = 13/(2*pi) = 2.06901426 feet Check: 2*pi*2.06901426 = 13 feet
circumference = 2*pi*radius or pi* diameter
First we have to find the radius because the area of a circle is pi*radius2: 2*pi*radius = 26 Rearrange the formula: radius = 26/2*pi radius = 4.13802852 units area = pi*4.138028522 = 53.79437075 square units
Circumference = 2*pi*radius = 26*pi inches
pi r2h =pi(20)2(26) =pi(400)(26) =(10400)pi =32656
area of a circle: radius x radius x pi(3.14) 26 x 26 x3.14 2122.64 squared units
The circumference of a circle with a radius of 13 is: 81.68 units.
Circumference = pi x diameter Hence Diameter = Circumference/pi Here Diameter = 26/3.1415 = 8.276 And Radius = Diameter/2, so Radius is 8.276/2 = 4.138 inches
radius = sq rt of (2122.64/pi) = 25.99340872 or about 26 units of measurement
If you mean a circle, simply multiply the radius by 2 x pi.
Using 3.14 as Pi the area of circle is: 530.66
pi*radius2 = 169*pi Divide both sides by pi then square root both sides to find the radius: radius = 13 and 2*13 = a diameter of 26 cm
IMPOSSIBLE circumference = 2*pi*radius if circumference = 2*radius: 2*radius=2*pi*radius 2*radius/(2*radius)=2*pi*radius/(2*radius) 1=pi pi= 1 therefore it is impossible to have a circumference that is twice that of the radius
