Question

what is the exact and approximate area of a circle with a diameter of 6 feet? For the approximate area, round your answer to the nearest tenths place

Answer 1

Answer:

Exact: 9.42

Approx: 9

Step-by-step explanation:

The area of a circle is pi*radius^2 (pi=3.14 r=radius ^2= power of 2/squared)

The diameter is two times the radius. So, we need to divide the diameter by two for the first step of solving this.

6/2=3

Now, we know the radius is 3.

Let's square it:

3^2= 3*3

3*3=9

Now, the last step is to multiply it by pi (3.14)
3.14*3=9.42

There we go! The area is 9.42 feet!
