So.. if hmm check the picture below, the radius is half that diameter
thus

simplify that away
now.. that's how much is in the cooler in cubic feet though, not in gallons
notice, our units were in feet, thus our volume is also in feet, just cubics
so. to know how many gallons, simply divide that by 231
Answer:
(x-9)^2 +(y-12)^2 = 225
Step-by-step explanation:
First find the length of the radius
If is the distance from the center to the point
d = sqrt( (x2-x1)^2 + (y2-y1)^2 )
= sqrt( (0-9)^2 + (0-12)^2)
= sqrt ( 81+144)
= sqrt(225)
= 15
The equation for a circle is
( x-h) ^2+ (y-k)^2 = r^2
(x-9)^2 +(y-12)^2 = 15^2
(x-9)^2 +(y-12)^2 = 225
Answer:
689 / 1000 is the answer
Step-by-step explanation:
zzzzzzzzzzzzz
Well, one way is to convert one of the numbers to the other. For example, if I have 3/5 and 0.5, I could convert 3/5 to a decimal. So, I would have 0.6 (3/5 converted to a decimal), and 0.5. Next, I would just add the two together to get my answer of 1.1
I use box method to solve this...:
100x^2+34x+49
I hope you wanted the formula! :)
