Question

Porter's coat has a diameter of 8 millimeters. What is the button's area

Answer 1

We can use the formula to solve for A, the area. The formula is:

A=1/4 · π · d^2.

So let’s use this to solve the diameter of the button.

1/4·π·8^2≈50.26548

We can then round to a final answer of 50.27.

Hope this helps!
