Answer:(x-3)^2+(y+6)^2=25
Step-by-step explanation:
Center Of The circle is at (3,-6)
Diameter=10
Radius(r)=10/2
Radius(r)=5
a=3
b=-6
Equation of circle=(x-a)^2+(y-b)^2=r^2
Equation of circle=(x-3)^2+(y-(-6))^2=5^2
Equation of circle=(x-3)^2+(y+6)^2=25
The nearest meter is 4 meters because the 7 would round the 3 to a 4, but a 4 wouldn't round up the 2. Even if the 4 rounded up the 2 to a 3, it still wouldn't be enough to round the 4 up to a 5. In other words, 4 and below will not round up anything, but a 5 or above will round up anything (as far as basics go).

Answer: choice B) 36</h3>
=================================================
Explanation:
The vertical sides, when read from left to right, can be divided to get this fraction: 9/90
Following the same order and direction, we divide the slanting corresponding sides to get: b/360
The fractions we constructed are equal to one another, as the triangles are said to be proportional.
We have the fraction 9/90 = b/360
Lets cross multiply and solve for b
--------------------
9/90 = b/360
9*360 = 90*b
3240 = 90b
90b = 3240
90b/90 = 3240/90
<h3>b = 36</h3>
--------------------
A quick way to do this may be to notice how the jump from 9 to 90 is "times 10" so the jump from b to 360 is also "times 10". Think in reverse to divide 360 over 10 and we land on 36 as our answer. This line of thinking does not work as simple for all proportional problems.
