If circumference(C) is given, then r = C/2(pi)
If area(A) is given, then r = (A/pi)1/2

What is the radius and area of a circle if the circumference is 157?
The radius and area of a circle if the circumference is 157 are:r = 25A = 1,960
What is the area of a circle with a circumference of 2 units?
You would need to include the radius to be able to determine the area.
What is the circumference of a circle with 7cm the radius?
The circumference of a circle with a 7cm radius is 44cm. The area is 154cm2
How do i find circumference and area of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
How do you find the circumference with no radius or diameter?
They would have to give you enough information to eventually get the diameter. If they gave you the area of a circle and asked for the circumference, you can determine the radius, and from the radius the diameter, and then the circumference. If they said "What is the circumference if the area of a circle is 36pi?" Area of a circle is pi*r2, which would give us a value for r = 6 Diameter is 2*r, or = 12. Circumference is d*pi, or 12pi
What is the area and circumference of a circle with the radius of 9.5 mm?
The area and circumference of a circle with a radius of 9.5 mm are:A = 284mm2C = 59.7mm
What is the area and the circumference of a circle?
area: pi times radius squared circumference: pi times radius
How is pi in relation to a circle?
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).
What is the circumference and area of a circle if the radius is 9.6 millimeters?
A circle with a radius of 9.6 millimeters has a circumference of 60.32 millimeters.
How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
What is the area and circumference of 18.4 feet?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
What is the circumference and the area of a circle with a radius of 3?
28.26=area 18.84=circumference
