centre of the circle =Midpoint of the diameter

centre of the circle=

( \frac{ - 8 + 4}{2}  , \frac{5 + 1}{2} ) = ( - 2 ,3)

radius of the circle=

\sqrt{(4 - ( - 2) ^{2} + (5 - 3 )^{2} }    =  \sqrt{36 + 4}  =  \sqrt{40 } = 2 \sqrt{10}

equation of the circle: (x+2)²+(y-3)² = 40

ie.. x²+4x+4+ y²- 6y+ 9=40

ie... x²+y²+4x-6y-27=0

this is the answer......

drek231 [11]

Answer:

The height of tallest building in Franklin is \[\frac{431}{8}\] feet or 53\[\frac{7}{8}\] feet.

Step-by-step explanation:

Given:

The height of tallest building in Mayville is 80\[\frac{13}{16}\] feet or \[\frac{1293}{16}\] feet. (Simplifying the fraction)

And the tallest building in Franklin is 2/3rd of the tallest building in Mayville.

So, multiply the height of Mayville with \[\frac{2}{3}\] to get the height of tallest building in Franklin.

Thus, the height of tallest building in Franklin will be,

h=\[\frac{1293}{16}\]\times\frac{2}{3}\\h=\frac{431}{8}\\h=53\frac{7}{8}

The height of tallest building in Franklin is \[\frac{431}{8}\] feet or 53\[\frac{7}{8}\] feet.
