Write a c program to find the Area of a Circle
বাংলায় সি প্রোগ্রামিং Part -12
—————————————————————————–
Area of a circle can simply be evaluated using the following formula.
Area = pi * r2
Where r is radius of circle and it maybe in float because value of pie is 3.14. It is approximately equal to 3.14159.
Pi is equal to the circumference / diameter of the circle.
Pi= Circumference / Diameter
Radius: The distance from the center to a point on the boundary is called the radius of a circle. It is represented by the letter ‘r’ or ‘R’. Radius plays an important role in the formula for the area and circumference of a circle.
Approach: Using the given radius, find the area using the above formula: (pi * r * r) and print the result in float.
