Given the radius of the circle is r = 10 cm.

The area of the circle is = π × r

This makes the solution = 3.14 * 10 * 10 square cm = 314 square cm.

Given the radius of the circle is r = 1.5 cm.

The area of the circle is = π × r

This makes the solution = 3.14 * 1.5 * 1.5 square cm = 7.1 square cm.
