What is the area of a circle with a diameter of 36 milimeters? use 3.14 for pi

1017.36mm²

Step-by-step explanation:

Since the diameter of that circle is 36mm, the radius would be equal to half the diameter

i.e. r =   (where d is the diameter of the circle)

r =

r = 18mm

Area of a circle = r² (where r is the radius of the circle)

Using 3.14 for ,

Area of the circle = (3.14 × 18²)mm²

                             = (3.14 × 18 × 18)mm²

                             = (3.14 × 324)mm²

                             = 1017.36mm²
