Answer:
r = 0.85 ft
C = 5.3407075111026 ftA = 2.2698006922186 ft²
Agenda:
r = radius
C = circumference
A = area
π = pi = 3.1415926535898
<span>√ = square root
</span>
Formula:
Circumference of a circle:
C = 2πr = πd
The first equation is

The second equation is

If you sum the two equations you'll cancel y:

And since the sum must be 11, we have y=9.
Answer:
Step-by-step explanation:
Convert the equation of a circle in general form shown below into standard form. Find the center and radius of the circle. Group the x 's and y 's together. Consider the x2 and x terms only. Complete the square on these terms. Replace the x2 and x terms with a squared bracket.
