Answer:
30/35=85.71%
Step-by-step explanation:
Observations with A,B,C: 30
Total Observations: 35
The circumference or perimeter of the circle has the formula 2*pi*r, where r is the radius of the circle. This could then be easily calculated:
C = 2*pi*r
53.38 = 2*3.14*r
53.38 = 6.28r
r = 53.38/6.28
r = 8.5 ft
Thus, the radius of the circle has a length of 8.5 feet.
3 x 5280 = 15840 feet
therefore the answer is 15840 feet (D)
Answers: 12-x=3 | x+3y=27 | 4y-10=14 | 1/3xy=18
Explanation: x=9 and y=6
12-(9)=3 | (9)+3(6)=27 | 4(6)-10=14 | 1/3(9)(6)=18
