If centred at origin, centre is (0, 0)

General equation of circle:

{ \boxed{ \bf{ {x}^{2} +  {y}^{2} + 2gx + 2fy   + c = 0}}}

but g and f are 0:

{x}^{2}  +  {y}^{2}   + c = 0 \\ but :  \\ c =  {g}^{2} +  {f}^{2}  -  {r}^{2}  \\ c =  { - 25}

There are 120 Calories in a 3/4-cup serving of cereal. How many Calories are there in 6 cups of cereal?
SpyIntel [72]
The first thing you have to do is divide 6 by 3/4 to 

6 divided by 3/4 is the same as 6/1 x 4/3 ( 24/3 = 8 )

Multiply 8 by 120

120 x 8 = 960

960 calories in 6 cups of cereal (that's a lot. don't eat it lol)

Hope I helped!
