The perimeter of a circle is finding the circumference of the circle

  --> calculated by the equation:   [tex]\pi D = 2\pi R[/tex]

  • D: diameter
  • R: radius

A semicircle has half of the circumference of the circle, thus the circumference equation is

 --> [tex]\frac{1}{2} \pi D = \frac{1}{2} *2*\pi *r[/tex]

We are given:

  • Diameter --> 17 in
  • [tex]\pi[/tex] = 3.14

Now let's calculate

[tex]\frac{1}{2} *3.14*17 = 26.69 in^2[/tex]

Hope it helps!
