1. Find area of a circle

A r = ≈ π π 2 and 3 .14)

A = 3.14 * 5 ^2

A= 3.14 * 25

Calculation step 3

Radius; extending from the center of a circle to the circumference.

Diameter; straight line passing through the center of a circle and meeting the circumference or surface at each end.

Area of a circle; A= ii R^

Area of a square; A= LW

II ( pi ) ; The 16Th letter of the greek alphabet used as the symbol

for the ratio of the circumference of a circle to its diameter.

3. Subtract the area of the circle from the area of the square.

100 - 78.5 = 21.5
