Answer:
Step-by-step explanation:
Given that,
The radius of circle, r = 50 feet
The central angle,
We need to find the area of the sector of a circle. The formula for the area of sector is given by :
So, the area f the sector of the circle is .
Using Pythagoras theorem, we know that 3² + 4² = 5², draw the 3-foot side and the 4-foot side with a right angle between them. The 5-foot side will fit to form a right triangle
<h3>How to use Pythagoras theorem to prove a right triangle?</h3>The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
Therefore,
c²= a²+ b²
where
- c = hypotenuse side
- a and b are the other legs.
Therefore,
3² + 4² = 5²
Hence,
Knowing that 3² + 4² = 5², draw the 3-foot side and the 4-foot side with a right angle between them. The 5-foot side will fit to form a right triangle
