Answer:
603.44 [in²]
Step-by-step explanation:
A = πr²/2 = 192.08 * π [in²] ≈ 603.44 [in²]
Answer:
The area of the semicircle having a radius of 19.6 meters is
603.68 [tex]m^{2}[/tex].
Detailed Answer:
The formula for the area of a circle is π[tex]r^{2}[/tex]. Therefore, the formula for the area of a semi-circle is ([tex]\frac{1}{2}[/tex] π[tex]r^{2}[/tex]).When the calculation is done
[tex]\frac{1}{2}[/tex] ×[tex]\frac{22}{7}[/tex] × 19.6 × 19.6 = 603.68 meters squared.
