Describe the error in finding the number of people who live in a circular region with a 7.5-mile diameter and a population density of 1550 people per square mile. 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

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
