**How To Find The Area Of A Circle In Terms Of Pi**. 4870.11 square inches (in²) use the this circle area calculator below to find the area of a circle given its radius, or other parameters. 1.05 ×1.05 = 1.1025 square meters.

The area of a circle is given by the constant π (pi) multiplied by the radius of the circle squared. 1.05 ×1.05 = 1.1025 square meters. Pi (π) is the ratio of circumference to diameter of any circle.

### Apply The Second Equation To Get Π X (12 / 2) 2 = 3.14159 X 36 = 113.1 Cm 2 (Square Centimeters).

Here we need to find the area of the circle, given: The formula for calculating the area of a circle is as follows. Find the area of a circle.

### That Means We Can Easily Find The Diameter By Doubling It.

Area of the circle = 3.14 × 10 × 10. Find the area of a circle given its diameter is 12 cm. Given any one variable a, c, r or d of a circle you can calculate the other three unknowns.

### For Example, If The Radius Is 5 Inches, Then Using The First Area Formula Calculate Π X 5 2 = 3.14159 X 25 = 78.54 Sq In.

So there are slightly more than 3 squares of the side r in the circle with radius r. The radius of a circle is half of the diameter, so we divide the diameter by 2. Radius of the circle = 10 cm.

### R = (Perimeter / Π) / 2

The calculations are done live: Using the same method as for the pentagons, we get: A = π r 2 = π d 2 /4.

### Pi Is Represented By The Symbol Π And Is A Number Which Is Approximately 3.141592.

Look at the given figure and identify the radius {eq}(r) {/eq} and the value of the central angle {eq. Area of smaller polygon = 1/2 x n x sin (360/n) area of larger polygon = n x tan (360/2n) where n is the number of sides of the polygon. Therefore, area of the circle is 314 cm 2.
