7. A circle has an area larger than 300 cm2and less than 650 cm2,with a center in the 1st quadrant.
a. Write an equation of this circle that fits this description (there are an infinite
number of possibilities).
b. Give a range of possible values for its radius (there will be a lower and upper
limit)

d≈7.07in

step-by-step explanation:

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
