Step-by-step explanation:
Answer: 408.2 ft^2
Step-by-step explanation:
A=2πrh+2πr2
A=2(3.14)(5)(8)+2(3.14)(5)^2
A=6.28*40+6.28*25
A=251.2+157
A=408.2 ft^2

The more painstaking way would be to divide the spinner up into 100 pieces, and shade in 5 of those pieces. Since 5/100 = 0.05 = 5% this means that landing on any of the 5 pieces has a 5% chance of happening.
A better way to do this is to use 20 slices instead. This works because 5/100 reduces to 1/20 (divide top and bottom by 5). Instead of shading in 5 slices, Mark should shade in 1. If you use a calculator, you should see that 1/20 = 0.05 = 5% as well.
The second option is more practical but even then a spinner with 20 sections is still a lot. I think it might be better for Mark to pull random numbers out of a hat, or let the computer generate random numbers.
