How to Find the Area of a Circle | Area of a Circle Step by Step - YouTube YouTube Start of suggested clip End of suggested clip So area equals pi times radius squared then we want to plug in our radius. So area equals pi timesMoreSo area equals pi times radius squared then we want to plug in our radius. So area equals pi times the radius of three inches squared then we would plug this into a calculator.

Area = length × breadthArea = l × b. Area = ? × radius × radiusArea = ? × r 2 ( ? = 3.14 )

Okay so the first step we're gonna fill in the gaps.

Area of a circle can be calculated by using the formulas: Area = ? × r2, where 'r' is the radius. Area = (?/4) × d2, where 'd' is the diameter.

Any equation expressed in terms of parameters is a parametric equation. The general equation of a straight line in slope-intercept form, y = mx + b, in which m and b are parameters, is an example of a parametric equation.

Basic Geometry Formulas Perimeter of a Square = 4(Side) Perimeter of a Rectangle = 2(Length + Breadth) Area of a Square = Side2 Area of a Rectangle = Length × Breadth. Area of a Triangle = ½ × base × height. Area of a Trapezoid = ½ × (base1 + base2) × height. Area of a Circle = A = ?×r2 Circumference of a Circle = 2?r.
