The diameter of a circle is 36 inches. What is the circle's area? use 3.14 for PI

but only

The area of the circle is the region occupied by it in the two dimensional plane.

Area of a circle is given by ;

The diameter of the circle is 36inches

‎ㅤ‎ㅤ‎ㅤ➙ Radius = D / 2

‎ㅤ‎ㅤ‎ㅤ➙ Radius = 36 / 2

‎ㅤ‎ㅤ‎ㅤ➙ Radius = 18 inches

Therefore, area :

➝ A = πr²

➝ A = 3.14 × ( 18 )²

➝ A = 3.14 × 324

➝ A = 1017.36

Solution:

We know that:

Finding the radius of the circle:

Finding the area of the circle:

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.
