# What is the area of a circle with circumference 2.6 miles?

Here is the answer to questions like: how to find the area of a circle with circumference 2.6 miles?

### Inputs:

 Radius: or Diameter or Circumference: Unit: inches feet yards miles kilometers meters centimeters millimeters

### Quote of the day...

The area of a circle with circumference 2.6 is 0.5379

### Formulae:

A = πr2 = π(d2)2
A = C2
π = 3.1415
A = area
C = circumference or perimeter
r = radius, d = diameter

### Area of a circle in terms of radius:

Area = π·r2 = 3.14·0.412 = 0.54 square miles(*)

### Area of a circle in terms of diameter:

Area = π·(d2)2 = 3.14·(0.832)2 = 3.14·(0.41)2 = 0.54 square miles(*)

### Area of a circle in terms of circumference:

Area = C2 = 2.62 = 6.76(4·3.14) = 6.7612.56 = 0.54 square miles(*)

(*) 0.53794370765061 miles, exactly or limited to the precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

### A circle of radius = 0.4138 or diameter = 0.8276 or circumference = 2.6 miles has an area of:

• 1.39315 square kilometer (km²)
• 1393150 square meter (m²)
• 1.39315 × 1010 square centimeter (cm²)
• 1.39315 × 1012 square millimeter (mm²)
• 0.5379 square mile (mi²)
• 1666200 square yard (yd²)
• 1.49958 × 107 square foot (ft²)
• 2.15939 × 109 square inch (in²)

Use the this circle area calculator below to find the area of a circle given its circumference, or other parameters. To calculate the area, you just need to enter a positive numeric value in one of the 3 fields of the calculator. You can also see at the bottom of the calculator, the step-by-step solution.

## Formula for area of a circle

Here a three ways to find the area of a circle (formulas):

A = πr2

A = π(d2)2

### Circle area formula in terms of circumference

A = C2

See below some definitions related to the formulas:

### Circumference

Circumference is the linear distance around the circle edge.

### Radius

The radius of a circle is any of the line segments from its center to its perimeter. The radius is half the diameter or r = d2.

### Diameter

The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. The diameter is twice the radius or d = 2·r.

### The Greek letter π

π represents the number Pi which is defined as the ratio of the circumference of a circle to its diameter or π = Cd . For simplicity, you can use Pi = 3.14 or Pi = 3.1415. Pi is an irrational number. The first 100 digits of Pi are: 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 ...

### Note:

If you input the radius in centimeters, you will get the answer in square centimeters (cm²), if in inches, will get the answer in square inches (in²) and so on ...

Circumference is often misspelled as circunference.
