Answer: 3,868 m²
Explanation:
The radius (r) of the big circle is 17 + 22 = 39
A = π·r²
= π(39)²
= 1521 π
The radius (r) of the small circle is 17
A = π·r²
= π(17)²
= 289 π
The area of the shaded region is the difference between the area of the big circle and the area of the small circle.
= 1521 π - 289 π
= 1232 π
= 1232(3.14)
= 3,868.48
