Answer :

The formula for the area of a circle is π r^2 which r is the radius or the half of the diameter.

Given :

The diameter of a circle is 9 cm.

On finding the radius,we need to half the diameter which is 9 cm

The Radius of the circle is 4.5

Solve :

( π = 3. 14 )

  • A = π r^2

  • A = (3. 14) (4.5)^2

  • A = (3. 14) (20. 25)

  • A = 63. 585

Hence the Area of the circle is 63.585 cm ^ 2
