1. Add all the sides 33 inches left and right and 75 inches. up and down.
Perimeter= 216
2. If 2/3 pounds is needed for 1 cheese cake and you have 2 pounds its not enough so 2 minus 2/3 will give you a mixed fraction : 1 over 1/3 or a decimal : 1.3

11a) You can see for yourself that the change in distance vertically is 8 and that horiz. is 6. Thus, the distance between (1,6) and (7,-2) is
d = sqrt(6^2 + 8^2) = sqrt(36+64) = 10 units (answer)
Answer:
41. 165.8 cm², 42. 101 m², 43. 75π ft², 44. 147π cm²
Step-by-step explanation:
41. 18x12=216, 3.14(4)²=50.24
216 - 50.24 = 165.76
42. 14x9=126, 5x5=25
126 - 25 = 101
43. πr² = (π)10²- (π)5² = 75π
44. πr² = (π)14²- (π)7² = 147π
