Answer 1

Answer:

3.14

Step-by-step explanation:

Hello! To get the formula we must first use the formula!

The formula is pi * r^2. In this case since r = 1, we know 1 * 1 = 1.

And since we are going to use 3.14 for pi, we can do 1 * 3.14 which is 3.14.

Hoped this helped ya :)

r = 1 unit

A = π×1²

= 3.14 units² (3s.f)
