The surface area of the cylinder should be 1130.97. I found this by using the formula a=2πrh+2πr2.
Good luck my bud.
Answer:
Step-by-step explanation:
We can split this into 20 triangles, each with an angle sum of 180 degrees.
So 180(20) = 3600 degrees.
Let b be the speed of the boat, and c be the speed of the current. Then:
20/b+c=2/3 hr
20/b-c=1 hr
2/3b+2/3c=20
b-c=20
Then:
b+c=30
b-c=20
2b=50
b=25 mph
c=5 mph
