Answer 1

Answer:

$3,744.45\ m^{2}$

Step-by-step explanation:

we know that

The area of a sector is equal to

$A=\frac{\theta}{360\°}\pi r^{2}$

where

$\theta$ ------> is the angle in degrees

r is the radius of the circle

In this problem we have

$r=45\ m$

$\theta=212\°$

assume

$\pi =3.14$

substitute the values

$A=\frac{212\°}{360\°}(3.14)(45)^{2}$

$A=3,744.45\ m^{2}$
