Find the shaded area of each figure. Round your answer to the nearest tenth if necessaery for #4-6

Answer 1

2) 486 ft²

4) 38 ft²

5) 27 ft²

6) 149 ft²

Explanation:

Just subtract the area of the unshaded part from the shaded part (as if the unshaded part wasn't there)

2) [shaded] (18 • 31.5) – [unshaded] (9 • 9) = 567 – 81 = 486

4) [shaded] (9 • 6) – [unshaded] (4 • 4) = 54 – 16 = 38

5) [shaded] (6 • 6) – [unshaded] (3 • 3) = 36 – 9 = 27

6) [shaded] (14 • 14) – [unshaded] (7 • 7)

= 196 – 49 = 149
