The area of a circle PQR with center O is 72cm. What is the area of sector POQ if angle POQ is 40

1 answer:

4 0

There are 360 degrees in a circle. If you simplify 40/360, you get how much of the circle the portion is. 40/360 simplifies to 1/9, which means that if you multiply 1/9 by 72, you get the area of the sector. Therefore, the area of sector POQ is 8.

✡ Answer: x=6.72 ✡

- - Solve:

- - First step is to cross-multiply:
- $7.5*x=4.2*12$
- $7.5x=50.4$

- - The next step is to divide both sides by the number 7.5
- $\frac{7.5x}{7.5} = \frac{50.4}{7.5} 
$


- - x=6.72
