Doug entered a canoe race. He rowed 3.5 miles in 0.5 hour. What is his average speed in miles per hour?

no he doesnt because "-16' is negatiive

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road

it is c!

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
