WebYou need the radius to work out the area of a circle, the formula is: Area of a circle = πR 2. This means: π = Pi is a constant that equals 3.142. R = is the radius of the circle. R 2 (radius squared) means radius × radius. Therefore a circle with a radius of 5cm has an area of: 3.142 × 5 × 5 = 78.55cm 2. A circle with a diameter of 3m has an area: WebTo calculate the area of a sector you need to know its central angle, θ and the radius. The area of a sector can then be calculated by using the following formula: πr 2 × (θ ÷ 360) Arcs A section of the circumference of a circle is called an arc.
