Circumference of a circle equals Pi times the double the radius C = 2 x 3.14 x radius C= 2 x 3.14 x 20 C = 125.6 The circumference of a circle with a 20 foot radius is 125.6 feet.
20
pi*r2 = 400*pi Therefore radius = 20 meters Cicumference = 2*pi* radius = 40*pi meters
Circumference = Pi * diameter. so Circumference = pi * 20 = 62.832
The circumference is pi x diameter, or 2 x pi x radius. In this case, 2 x pi x 10, approximately 20 x 3.14 = 60.28 meters.
Circumference = 2*pi*r = 125.66 metres
The radius of this circle is 10 units.
The radius of a circle whose circumference is 40pi is 20 units.
If the circumference of a circle is 62.8 meters the diameter is: 20 meters.
Circumference of a circle equals Pi times the double the radius C = 2 x 3.14 x radius C= 2 x 3.14 x 20 C = 125.6 The circumference of a circle with a 20 foot radius is 125.6 feet.
20
pi*r2 = 400*pi Therefore radius = 20 meters Cicumference = 2*pi* radius = 40*pi meters
First we have to find the radius: pi*radius2 = 400*pi square meters Divide both sides by pi and then square root both sides: radius = 20 meters 2*pi*radius or pi*diameter = circumference 2*pi*20 = 40*pi meters
radius = 20/(2*pi) = 3.183098862 inches
Circumference = Pi * diameter. so Circumference = pi * 20 = 62.832
Multiply the radius by (2 x pi).
Formula for finding the circumference of a circle = 2*pi*radius or pi*diameter. 2*pi*10 = 62.83185307 metres. pi*20 = 62.83185307 metres. This can be rounded up as the circumference being 63 metres, correct to the nearest whole metre.
