Answer:

40π in²

Step-by-step explanation:

The area (A) of sector ODC is calculated as

A = area of circle × fraction of circle

= πr² × $\frac{72}{360}$

= π × 10² × $\frac{1}{5}$ = $\frac{100\pi }{5}$ = 20π cm²

Sector OAB is congruent to sector ODC, thus

area of shaded regions = 2 × 20π = 40π in²
