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>
The sum of b and f is b+f
Three times this sum is 3(b+f)
Answer:
i dont know sorry
Step-by-step explanation:
24% of 225 is 54, so you do 225+54=279 so 279 is the correct answer :)
276 divides by 4 = 69
So 3x69 = 207 + 276 = $483
