The area, in square inches, outside the smaller region, but inside the larger region is 99π
<h3>How to determine the area, in square inches, outside the smaller region, but inside the larger region?</h3>
The given parameters are:
Radius, r1 = 1 inch
Radius, r2 = 10 inches
The area, in square inches, outside the smaller region, but inside the larger region is calculated as
Area = π(R^2 - r^2)
This gives
Area = π(10^2 - 1^2)
Evaluate the difference
Area = 99π
Hence, the area, in square inches, outside the smaller region, but inside the larger region is 99π

The number of students who chose not to study Spanish in their senior year is 124.
In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
Given that
56% Students studied Spanish, which means 44% did not study Spanish.
In mathematics, a ratio shows how many times one number contains another.
Hence if the ratio is:
56 : 44 = 14:11
Then, the number of students who did not study Spanish is:
(14/11)×98 = 124.
Therefore the correct answer is 124.
