Question

What is the area of a circle with a radius of 1

Answer 1

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

r being your radius

A = $\pi r^{2}$

Substitute 1 in for r

A = $\pi (1)^{2}$

A = $\pi$

Answer 2

Answer:

π or 3.14

Step-by-step explanation:

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

$A=\pi r^2$

2. Solve for area of a circle.

$A=\pi r^2$

$A=\pi 1^2$

$A= \pi$

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