Question

What is the area of the following circle? Either enter an exact answer in terms of π or use 3.14 for π and enter your answer as a decimal.

PLEASE HELP!!!!!!!!!!

Answer 1

π square units.


The formula for the area of a circle is
`πr^(2)`, where the radius is represented by r. Also, the radius is half of the diameter.

Since half of the diameter is 1 unit, that is the radius, making our formula
`π*1^(2)`, or
`π*1*1`. The identity property of multiplication shows that multiplying by 1 doesn’t affect the result, so we can remove the multiplication by one. This leaves us with just pi, so the answer is π square units.
