Question

area of one half - circle=$\frac{1}{2}picdot14^{2}$ = square ft 28$pi$ 14$pi$ 98$pi$

Explanation:

Step1: Calculate the area of the half - circle

The formula for the area of a full - circle is $A = \pi r^{2}$. For a half - circle, the area formula is $A=\frac{1}{2}\pi r^{2}$. Given that the radius $r = 14$ ft.
Substitute $r = 14$ into the formula: $\frac{1}{2}\pi\times14^{2}=\frac{1}{2}\pi\times196$.

Step2: Simplify the expression

$\frac{1}{2}\times196\pi=98\pi$ square ft.

Answer:

$98\pi$ square ft
