The area of a circle is pi * radius squared. the diameter of a circle is two times the radius, so the radius of this circle is 40. so the area of this circle is 40^2 times pi, which is about 5026.55.

MrRa [10]

Answer:

12

Step-by-step explanation:

First substitute the equation with the variable replacements given:

-r/9 + 5x <--- Before

-27/9 + 5(3) <--- After

Next Solve the parts of the Equation

-27/9 + 5(3)

-3 + 15 <--- -27 divided by 9 is -3, 5 times 3 is 15.

= 12 <--- 15 - 3 = 12.

I hope this helps!
