Answer: 84 mm is MAYBE the answer.
Answer:
B, 70pi ft2
Step-by-step explanation:
The equation to find surface area of a cylinder is 2(pi)(r)(h)+2(pi)(r)^2. So now plug the numbers in.. 2(pi)(5)(2)+2(pi)(5)^2 now, simplify. 20pi+50pi= 70pi ft2.
D. no solution
Because they never found each other, the point they cross on is the solution.
