2(10)+5 = 25. The answer is A
1. Need distance formula to find how long it is then cut it in half to find the radius....d= 10.....r= 5
Need midpoint formula to find the center....midpoint= (-1, -1)
(h,k) in the equation of a circle is the center, "r" is the radius. When you plug in the center, you have to put the opposite signs...so......
equation of a Circle = (x - h)^2 + (y - k)^2 = r^2 = (x + 1)^2 + (y + 1)^2= 25
2. A= pi(r^2)
200.96= 3.14(r^2)
64 = r^2
r = 8
Then to find the circumference, C= 2(pi)(r) = 2 (3.14) (8) = 50.24
For 3 and 4, is there a diagram?
A quilt design uses parallelogram-shaped pieces that have a base measure of 4 inches and a height of 6 inches. If 15 pieces are used in the quilt, what is the total area of the parallelogram-shaped pieces in the quilt?
1.225 in.
2.360 in.
3.(450 in.)
4.900 in.
<span> 15*4*6 = 360 sorry but I only have the answers for number 1 and 2

Answer:
A cage holds 6 black cats and 9 white cats, if two cats escape what is the probability of both cats being white?
Step-by-step explanation:
This involves two events, each with their own probability. Because both the first AND the second have to happen for this problem, you will MULTIPLY the wo individual probabilities.
Total cats = 15, White cats = 9
Probability first escaped cat is white = 9/15
One white cat has now escaped, so we now have Total cats = 14, White cats = 8
Probability second escaped cat is white = 8/14
Now MULTIPLY because this is an AND probability problem. (9/15)(8/14) = 72/210 = 12/35
