Question

A banner is made of a square and a semicircle. The Square has side lengths of 26 inches. One side of the square is also the diameter of the semicircle. what is the total area of the banner? use 3.14 for \pi.

Answer 1

The area of a circle of diameter d is given by
.. A = (π/4)d^2
so the area of a semicircle with that diameter will be half that.

The banner has area
.. (26 in)^2*(1 +π/8) ≈ 941.33 in^2
