The radius of the given circle is 2.5 cm, i.e. r = 2.5 cm.

Here the value of Pi = 3.14

This makes the solution = 3.14 * 2.5 * 2.5 square cm = 19.625 square cm.

The area of the given circle with radius 2.5 cm is 19.6 cm

The radius of the given circle is 11 cm, i.e. r = 11 cm.

Here the value of Pi = 3.14

This makes the solution = 3.14 * 11 * 11 cm = 379.94 cm

The area of the given circle with radius 11 cm is 379.9 cm
