The diameter of a circle is 12 inches. What is the area of the circle. Use 3.14 for the radius

R=6

A=36 Or 113.09733552923(113.1 rounded to the nearest tenth)

Step-by-step explanation:

R=d/2

12/2=6

A=

12/2=

6*6=36

(36*3.14=113.09733552923 if you don’t have pi symbol)

113.09733552923 rounded=113.1

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
