Answers- D) 4.4π & Area-44
1. To solve the first equation we must use the equation for find Circumfrence C=2πr. Our r is 2.2 so our equation would look as C= 2π2.2. Since 2 and 2.2 are whole numbers we can multiply them by one another and that gives us 4.4. So our final answer would be C= 4.4π or D)
2. The best way to solve for our area would be to cut the shapes straight down the middle. Now the two shapes will be 7x4 and 4x4. 7x4 is 28 and 4x4 is 16. To get our final answer we would add 28 and 16, which is 44. To show this one your work draw a line going straight down to cut the shapes into a square and a rectangle. (view source)
