Answer:
C = 2πr.
Step-by-step explanation:
To calculate the circumference of a circle, use the formula C = πd, where "C" is the circumference, "d" is the diameter, and π is 3.14. If you have the radius instead of the diameter, multiply it by 2 to get the diameter. You can also use the formula for circumference of a circle using radius, which is C = 2πr.
Answer:
x2+y2−10x−12y+60=0
Step-by-step explanation:
The standard form of the equation of a circle is usually given in the form;
![(x-a)^{2} +(y-b)^{2}=r^{2}](https://tex.z-dn.net/?f=%28x-a%29%5E%7B2%7D%20%2B%28y-b%29%5E%7B2%7D%3Dr%5E%7B2%7D)
The center of the circle is (a, b) while r denotes the radius.
The general form of the equation of a circle is obtained by expanding the brackets, collecting like terms and simplifying.
The standard form in this case has been given as;
(x−5)^2+(y−6)^2=1
We simply open the brackets and simplify to obtain the general form;
(x−5)^2 = (x−5) (x−5)
= x^2 -5x -5x +25
= x^2 -10x +25
(y−6)^2 = (y-6) (y-6)
= y^2 -6y - 6y +36
= y^2 -12y +36
(x−5)^2+(y−6)^2 = x^2 -10x +25 + y^2 -12y +36 = 1
x^2 -10x +25 + y^2 -12y +36 = 1
x^2 + y^2 -10x -12y +25 + 36 = 1
x^2 + y^2 -10x -12y + 60 = 0
Answer:
So first we have to figure out what $1200 per month for 12 months is since it was a year. 1200x12=14,400 a year which is outrageous for an apartment just saying.
Then we find out what 12% of the 1200 is and then add it to 1200.
To find the percentage of that we need to know how many times 12 fits into 100% 12 fits into 100 a total of 8.33333333333 times.
So now we divide 1200 by 8.33333333333 to see what 12% of it is.
1200 divided by 8.33333333333 is 144. So 1200+144=1344.
Now since one of the nine years has passed already we only have 8 remaining.
Now we see what 1344 a month for 12 months is 16,128 a year.
Now we multiply 16,128 by 8 to get the outcome of 8 more years. So 16,128x8=129,024
