Question

What is the area of a circle with a diameter of twenty-eight meters? Use twenty-two sevenths for pi.

Answer 1

Well you know the area of a circle is

\[\pi r^2\]

We have the diameter.....but we need the radius for the equation...so divide 28 in half to get 14...now have have all we need since we know to use 22/7 for pi

\[Area = \frac{ 22 }{ 7 } \times 14^2\]
