What is the area of the circle?

**Note:**Area of a circle = πr

^{2}, where r is the radius of the circle.

**Example:**What is the area of a circle whose diameter is 10 cm?

**Given:**Diameter(d) = 10cm; So, Radius(r) = Diameter/2 = 10/2 = 5cm

**Area of a circle:**πr

^{2}= π x 5

^{2}= π x 25 =

**25π sq cm**
