The area of the shaded region is 294 square inches ⇒ 2nd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- From the attached figure

- There are two congruent circles inscribed in a circle

∵ The two congruent circles touch each other at one point and

   each one touch the big circle at one point

∴ The centers of the three circles and the touches' points lie on

   the same segment which is the diameter of the big circle

∴ The diameter of the big circle = the sum of the diameters of the

   inscribed circles

∵ The radii of the congruent circle = 7 inches

∵ The diameter of a circle is twice its radius

∴ The diameter of each inscribed circle = 2 × 7 = 14 inches

∴ The diameter of the big circle = 14 + 14 = 28 inches

∵ The radius of a circle is half its diameter

∴ The radius of the big circle = 1/2 × 28 = 14 inches

- The area of the shaded part is the difference between the area

  of the big circle and the sum of areas of the congruent circles

∵ The area of a circle = πr²

∵ The radius of the big circle is 14 inches

∵ π = 3 ⇒ given

∴ The area of the big circle = 3(14)² = 588 inches²

∵ The radius of each congruent circle is 7 inches

∴ The area of each congruent circles = 3(7)² = 147 inches²

∴ The area of the two congruent circles = 2 × 147 = 294 inches²

∵ Area shaded = area big circle - area two congruent circles

∴ Area shaded = 588 - 294 = 294 inches²

* The area of the shaded region is 294 square inches

$655.61 which is option c

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
