Answer: The area of shaded section is 491.07 cm²
Step-by-step explanation:
Given: Radius of the circle = 25 cm
Now as shown in figure the shaded region is a quadrant.
Therefore the central angle is 90°
Now as we know
Area of sector is given by
where r is radius and
is central angle
So we have
Hence, the area of shaded section is 491.07 cm²
The units that we should use are gallons per day, we get:
<h3>Which units should we use?</h3>
We want to express the fact that every day you use 2.4 gallons of gasoline.
So we have two types of units in the above sentence, time (in days), and volume (of the gasoline consumed).
Then we conclude that the units that we should use is volume over time, particularly, gallons per day.
So we can represent that measure as:
