Answer:
884. D
885. C ( changed my answer)
886. B
887.A
For number 844, the diameter if the fan is 12 inches. To find Circumference, multiply the radius by two and then pi. The radius of the fan is 6, multiplied by 2 is 12, and multiplied by pi gives 12 times pi.
885 says half of the area gives the circumference. So we can write a formula, (pi*r^2)/2=2*pi*r. If the radius were 4, this would make the equation true. So the answer is 4.
886. Circumference=2*pi*r
r=6.78
2*pi*6.78
13.56*pi
887.
3*3=9
13-3=10
10*23=230
230+9=<u>239</u><u> </u><u>units</u><u> </u><u>squared</u>
1 cup = 2 half cups
multiply 2 half cups with 11
11 x 2 = 22
22 half-cups is your answer
hope this helps
Answer:
the answer of x is 3 because 3^3 equal to 27
B is the correct answer. The $20 flat fee is the 20 in the equation. The 4 dollars per hour is the 4h in the equation. The $30 is the total amount at the end of the equation.
