The perimeter of a circle is 25.12 meters. If the radius is increased by a quarter, how much will the perimeter and area increase?

The perimeter of a circle is 25.12 meters. If the radius is increased by a quarter, how much will the perimeter and area increase?

If the original radius is 25.12 / 3.14 = 4, the area is 4 * 4 * 3.14 = 50.24
The radius is 4 + 4 * 1 / 4 = 5 after increasing 1 / 4
The perimeter is 5 * 2 * 3.14 = 31.4
The area is 5 * 5 * 3.14 = 78.5
So the perimeter increased by 6.28 and the area increased by 28.26
