Question 2
The formula for the circumference of a circle was used instead of the formula for the area of a circle.
The diameter was substituted into the formula for the area of a circle instead of the radius.
The expression π⋅7.52 should be in the numerator of the fraction, not the denominator.
The expression π⋅7.52 simplifies to 56.25π2, not 56.25π.
Question 3
Correct the error. Round your answer to the nearest whole number.
The number of people who live in the region is about
