Answer:
Center (2,4) , radius=3, h=2 v=4 & r=3
Step-by-step explanation:
Ok so in order to find the center of the circle, use the graph (like you can see that the x is 2,if you count down from 5 to the left. the y is 4,because it's below 5 in the y pole).So the center is (2,4)
Now, in order to find the length of the radius, you need to do the following:
Take the center point (2,4) and the point where the circle ends (2,1) . Because radius is a straight, you can substract the y values of the two points : 4-1=3
As you can see in the equation, the h symbolizes the x of the center point and the v symbolizes the y.The r is the radius that we already found(3)
So it's shouldn't be a problem now to find the equation of the circle,simply replace the values with their numbers:
(x-2)^2 + (y-4)^2 = 9

1/7 the speed of a cheetah is 10 mph because an average cheetah can run 70 miles per hour. This means time to do some division. Envision the denominator of 1/7 (7) as 70 and then the numerator (1) should be 10. Divide 70 by 7 should be 10. Hope this helps.
Answer:
Area is 0.34 ft²
Step-by-step explanation:
A=L•w
P=2L+2w
L=w/2-1
31=2(w/2-1)+2w
31=w-2+2w
33=3w
11=w
L=w/2-1
=11/2-2/2
L=9/2
Aft=L/12•w/12
=(9/2)/12•11/12
Aft=0.34
