Find the area A of the sector of a circle of radius 50 feet formed by the central angle

kozerog [31]

Answer:

$A=6250\ feet^2$

Step-by-step explanation:

Given that,

The radius of circle, r = 50 feet

The central angle, $\theta=5\ radian$

We need to find the area of the sector of a circle. The formula for the area of sector is given by :

$A=\dfrac{1}{2}r^2\theta\\\\=\dfrac{1}{2}\times 50^2\times 5\\\\A=6250\ feet^2$

So, the area f the sector of the circle is $6250\ feet^2$ .
