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
</span>
AB+BC+AC-12=AC+CD+AD
AB+BC-12=CD+AD
AB+BD+CD-12=CD+AD=BD
AB+BD-12=0
AB=12cm
The rationalized form is:
Step-by-step explanation:
Given
To rationalize a denominator, we multiply the numerator and denominator of a fraction with conjugate of the denominator
The conjugate of denominator is:

Answer:
use formala
c^2+a^2=b^2
fill out the numbers
the corner there is 90 degrees and the top corner is 30 this is because all sides of a triangle calculated always equeal 180
Step-by-step explanation:
Answer:
3/2
Step-by-step explanation:
to divide fractions you just have to multiply them by the reciprocal.
so, instead of 3/4 divided by 1/2
it's changed to 3/4 * 2/1
then you just multiply the numerators together and the denominators together
3*2/4*1
6/4
3/2
3/2
Goodluck with your schoolwork/homework.
