To find the area of a circle, you have to use the area formula:

r being your radius

A = [tex]\pi r^{2}[/tex]

Substitute 1 in for r

A = [tex]\pi (1)^{2}[/tex]

A = [tex]\pi[/tex]

Answer:

π or 3.14

Step-by-step explanation:

1. Set equation to solve for area of a circle.

[tex]A=\pi r^2[/tex]

2. Solve for area of a circle.

[tex]A=\pi r^2[/tex]

[tex]A=\pi 1^2[/tex]

[tex]A= \pi[/tex]

If π is 3.14, you're answer would be 3.14.
