Write the equation of the graph below

Step-by-step explanation:

This is a parabola with a vertex at h = 4 and k = 5; the graph goes through the coordinate x = 6 and y = 6. We will use those 4 values to fill in the equation:

and this will allow us to solve for the value of a:

and

and

6 = 4a + 5 and

1 = 4a so

and the equation is

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

pls mark as brainliest

i agree because i see the other persons thinking is clear
