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

So find how much was eaten 1/6 and 2/3=eaten add 1/6 and 2/3 convert bottom number to same 2/3=4/6 1/6+4/6=5/6 5/6 eaten 3-5/6= 2+1-5/6= 2+6/6-5/6= 2+1/6 2 and 1/6 waffles left
