Answer:
2.09 sq. units
Step-by-step explanation:
We can simply use the formula for area of a sector of a circle.
Area of sector = 
Where
is the angle and r is the radius.
<em>It is given that the angle is 15 and radius is 4. We plug them in and find the area:</em>
<em>
</em>
<em />
<em>Thus area of sector is 2.09 sq. units.</em>
The average is 822 I believe.
You need to use the equation Distance (miles)=Rate (miles/hour) x Time (hours)
Brandi: 2.5 miles=rate (1/2 hour) r=5 miles per hour
Sharna=3.5 miles= rate (3/4 hour) r = 7 miles per hour.
Therefore brandi jogged at a slower rate.
One sixth of 60km would be 10km.
