Answer:
see explanation
Step-by-step explanation:
The area of the shaded portion is the area of the outer circle subtract the area of the inner circle
area of larger circle = πr² ← r is the radius = 11
area = π × 11² = 121π
area of smaller circle = πr² ← r = 9
area = π × 9² = 81π
-----------------------------------------
shaded area = 121π - 81π = 40π m² ≈ 126 m²
I think the easiest way to think about this is to put 0.25 into fractional form. 0.25 = 1/4 because 4 divided into 1 = 0.25
So 1/4 added to 2/9 will give us a fraction (rational number). Of course to determine what the fraction is, we have to get a common denominator.
(In case you wanted to know what that rational number is: The least common denominator would be 36. So changing 1/4 by multiplying top and bottom by 9 gives 9/36 and changing 2/9 by multiplying top and bottom by 4/4 gives 8/36 and adding 9/36 to 8/36 gives 17/36 - a rational number.)
