Answer 1

Answer:

38.5

Step-by-step explanation:

The formula for the area of the circle is $\pi rx^{2}$.

Since you have the diameter and you're told to use 3.14 as pi, all you need to do is to substitute.

The diameter is also 2 times the size of the radius so you divide 7 by 2.

So $(3.14)(3.5)^{2} = 38.5$
