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>

Is 50 a perfect square ? Explain your answer please 
xeze [42]
No, 50 is not a perfect square.  A perfect square is any number that can be divided by any number to get the quotient as the same number AND the quotient must be rational.  When you divide 50 so that the quotient equals the divisor, you will get an irrational number.  Therefore, 50 is not a perfect square.

Rotate triangle P 90° clockwise about the point (2, -1).<br>​
dlinn [17]

Answer:

Step-by-step explanation:

If we are rotating about the point (2,-1) , then we first need to translate the triangle two points to the left so that point P is at location (2,-1). Once we have that we rotate everything 90 degrees clockwise, while maintaining the same distance and angles between each point in the triangle. After doing this we will get the triangle seen in the attached picture below. Which is fully rotated 90 degrees clockwise about the point (2,-1)
