How do you calculate area of a circle?
Area is the measurement of the size of the surface. The area of a circle is Ï€ (Pi) times the radius squared. The distance around the circle is called as circumference. Distance across the circle is called as Diameter. Learn how to find area of the circle from this step by step tutorial.
Let us learn here how to calculate the area of a circle.
Area of a Circle Formula:
Area of a Circle A = π x radius2
π (Pi) is a constant which is equal to 3.14
Let us consider an example to find the area of a circle whose radius is 7cm?
Step 1: Consider the values given,
R = 7 cm
Step 2: Applying the values in the formula
A = Pi x Radius2
A = 3.14 x 72
A = 3.14 x 7 x 7
A = 3.14 x 49
A = 153.86 cm2
Area of Circle Calculation Result:
Area of Circle (A) = 153.86 cm2
