What is the area of a circle with a circumference of 12?

Updated: 4/28/2022

circumference = 2 x π x radius

⇒ radius = circumference ÷ 2π

area = π x radius2

= π x (circumference ÷ 2π)2

= circumference2 ÷ 4π

= 122 ÷ 4π

= 36/π

≈ 11.46 square units.

Area of a circle with a 12 inch circumference?

The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.

What is the area of a circle if its circumference 12 pie?

The area of a circle if its circumference 12pi is: 113.1 units squared.

Is the Area of a circle and circumference of a circle have the same thing?

No,Circumference is like the perimiter and Area is the whole circle.

If the diameter of a circle is 12 inches what is the circumference of the circle?

If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).

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
