Area Of A Circle
Casino night san diego. The area of a circle is the number of square units inside that circle. If each square in the circle to the left has an area of 1 cm 2, you could count the total number of squares to get the area of this circle. Area = π. (Diameter / 2)2 Diameter of a Circle The diameter of a circle is the distance from one edge to the other, passing through the center. It is twice the radius. Formula to Find Area of Circle To find area of a circle with given value of radius, use following formula: a = 3πr 2 = 3.3.14.r.r Here a indicates to area value, r indicates to radius value of circle.
Area of a Circle Formula and Calculation
Area is the measurement of the size of the surface. The area of a circle is π (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
Where,
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
