Answer:

Step-by-step explanation:
To write the equation of a circle, use the formula
where the center of the circle is (h, k).
This means the equation is
.
Find the radius r by dividing the diameter of 10 in 2. The radius is 5.
So the equation of the circle is 
i cannot help with all this but 16 would be 33 ft
Answer:
35.4%
Step-by-step explanation:
(100/80) x 27.6
basically 1 of 80 is 1.25 and multiply 1.25 times the money jaylon spent sorry i am really bad at explaining only good at solving
Answer:that's easy
Step-by-step explanation: to find the length of the circle you times it you will find the answer
Answer:
Infinitely many solutions.
Step-by-step explanation:
Let's begin by carrying out the indicated multiplications, which must be done before any addition or subtraction:
2(8r+5)-3=4(4r-1)+11 becomes 16r + 10 - 3 = 16r - 4 + 11.
Subtracting 16r from both sides, we get 10 - 3 = - 4 + 11, or 7 = 7
This is always true, so we can conclude that this equation has infinitely many solutions.
