Question

A cathedral window is built in the shape of a semicircle If the window is to contain three stained glass sections of equal size what is the area of each stained glass section? Express answer to the nearest square foot

• A. 1 sq. ft.
• B. 3 sq. ft.
• C. 13 sq. ft.
• D. 26 sq. ft
• E. Answer required

Answer 1

The correct option is E Answer required

Area of semicircle with radius r$=\frac{1}{2}\pi r^2$
Here, $r=\frac{5}{2}$
$\therefore$ area of window$=\frac{1}{2}\times \pi \times \frac{25}{4}=9.82$sq. ft
Size of each stained glass$=\frac{9.82}{3}\approx 3$sq. ft
Option B is correct.
