The area of the shaded region (using 3.14 for pi):

9 π - 4.5 π = 4.5 * 3.14 = 13.5 + 0.63 = 14.13 m^2

The formula for the area of a circle is:

A = πr²

Step 1 - Find the area of the large circle

r = 3

A = π3² = 9π

Step 2 - Find the area of *one* of the smaller (unshaded) circles

r = 1.5

a = π(1.5)² = 2.25π

Step 3 - Subtract *two* of the smaller circles from the larger circle.

9π - 2(2.25)π

= 9π - 4.5π

= (9 - 4.5)π

= 4.5π

Step 4 - Calculate the approximate area using the rational approximation of π ≈ 3.14

4.5 * 3.14

= 14.13 m²

Area = πR² - 2πr² = π(R² - 2r²) = 3.14(3² - 2*(3/2)²) = 14.13 m^2
