A ring-shaped region is shown below. Its Inner radius is 11 cm, and its outer radius is 17 cm.

Find the area of the shaded region. Use 3.14 for pi. Do not round your answer.

527.52 cm²

Step-by-step explanation:

Area of the shaded region = area of the outer circle - area of the inner circle

Area of circle is given as πr²

Radius of inner circle = 11 cm

Area of outer circle = 17 cm

π = 3.14

Thus:

Area of shaded region = 3.14*17² - 3.14*11²

= 907.46 - 379.94

= 527.52 cm²
