He rode 80miles because 6 hoursis a long time to only make it 80 yards,feet,or inches
Well, all you have to do to solve this is multiply 850 times 10, which is 8,500, so that means there are 8 thousands.

38 yard piece for each student and there are 16 students:
38*16=608
608 yards needed for your class
Answer: 423.11 m^2
Step by step explanation:
Area of a circle formula pi*r^2
First solve the area of the big circle
3.14*21^2=1384.74 m^2
Now find the are of the smaller circle
r=21-3.5=17.5
3.14*(17.5)^2=961.63 m^2
Now we can minus the small area off the big area to get the shaded area.
1384.74-961.63=423.11 m^2
So the area of the shaded region is 423.11 m^2
