9514 1404 393
Answer:
14.09 square units
Step-by-step explanation:
The desired area is the area of the full circle, multiplied by the fraction that is shaded. That fraction is the ratio of the sector central angle to the central angle for a whole circle: 42°/360°.
A = πr²(d/360)
A = 3.14159(6.2²)(42/360) ≈ 14.09
The area of the shaded sector is about 14.09 square units.
To find the total cost, you need to add these numbers together
![1.89 + 3.19 + 2.29 = 7.37](https://tex.z-dn.net/?f=1.89%20%2B%203.19%20%2B%202.29%20%3D%207.37)
you get 7.37 as your answer, but you need to round this to the nearest whole number.
rounding 7.37 will make it 7.
the total cost is about $7
