Answer:

50π

Step-by-step explanation:

You can use the area of a circle formula to find the area of a semicircle:

A = π[tex]r^{2}[/tex]

Then, substitute the value of the radius and square it:

A = 100π

If a circle with the same radius had an area of 100π, the area of the semicircle would have an area 1/2 that:

100π/2 = 50π

Answer:

39.25 in²

Step-by-step explanation:

Diameter = 10 in

Radius r = 10/2 = 5 in

[tex]Area = \frac{\pi r^{2}}{2}\\\\=\frac{3.14*5*5}{2}\\\\\\=\frac{78.5}{2}\\\\=39.25[/tex]
