Circumference = 2*pi*radius
Area = pi*radius2
The radius and area of a circle if the circumference is 157 are:r = 25A = 1,960
The circumference of a circle with a 7cm radius is 44cm. The area is 154cm2
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
The circumference of a circle with a radius of 5 centimeters 157.0796...The area of a circle with a radius of a 5 centimeters is 78.5398...
The area and circumference of a circle with a radius of 9.5 mm are:A = 284mm2C = 59.7mm
area: pi times radius squared circumference: pi times radius
A circle with a radius of 9.6 millimeters has a circumference of 60.32 millimeters.
28.26=area 18.84=circumference
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
