Answer:
(x - 5)^2 + (y - 6)^2 = 64
Step-by-step explanation:
Every circumference is in the form:
(x - xc)^2 + (y - yc)^2 = r^2
Where xc is the x of the center. Yc is the y of the center. r is the radius. We just plug in the values and we're done.
Equation of a circle is:
<span>(x−h<span>)2</span>+(y−k<span>)2</span>=<span>r2</span></span>
h is the x-coordinate of the center and k is the y-coordinate of the center. Even though the formula has minus signs, those are positive numbers. If there were plus signs in there, the numbers h and k would actually be negative. Now since you're centered at the origin, that means h and k are 0, so you'd just have this:
<span><span>x2</span>+<span>y2</span>=<span>r2</span></span><span>
Now since your radius is 7, just square it and replace r^2 woth that value :)</span>
7g + 3g - 10 + 3 = 43
(first combine likes terms)
10g - 7 = 43
(then add 7 to both sides)
10g - 7 = 43
+7 +7
10g = 50
(then divide by 10 to get what g is equal to)
10g = 50
/10 /10
g = 5
Answer:
Step-by-step explanation:
#We use the base diagonal and the height diagonal to calculate the beam's height:
#The volume of the beam can then be calculated as:
Hence, the beam's volume is 
A right angle always has 90 degrees. So this is false.
