Question

What is the area of a sector of a circle with of 5 meters and subtended by a central angle of 180 degrees. Around to two places

Answer 1

Answer:

$A=39.26\ m^2$

Step-by-step explanation:

Given that,

The radius of a circle, r = 5 m

The central angle is 180 degrees

We need to find the area of a sector of a circle.

The formula for the area of sector of a circle is given by :

$A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{180}{360}\times \pi \times (5)^2\\\\A=39.26\ m^2$

So, the area of the sector of a circle is $39.26\ m^2$.
