Question

This diagram to the right represents a small stage in the shape of a SEMIcircle (half of a circle). Find the area of the stage. ***Diameter of the semi circle is 10 yards

Answer 1

above is the answer

Explanation:

Area of a circle=

`\pi {r}^(2)`

but this Is a semicircle so you divide it by 2 as in

`a = \frac{\pi {r}^(2) }{2}`

so d=2r so r=5yd

A=5×5 pie/2

=25 pie/2=12.5 yards
