How to work out the area of a circle with pi
WebYou can work out the Area of a Sector by comparing its angle to the angle of a full circle. Note: we are using radians for the angles. This is the reasoning: A circle has an angle of 2 π and an Area of: πr2 A Sector has an angle of θ instead of 2 π so its Area is : θ 2π × πr2 Which can be simplified to: θ 2 × r2 WebExample 1: area of a rectangle. Work out the area of the rectangle. Write down the formula. \text {Area }= base \times height Area = base×height. 2 Substitute the values into the formula. Here the base is 11cm 11cm and the height is 4cm. 4cm. Area=11 \times 4 Area = 11×4. 3 Do the calculation.
