#1. I think the answer is B because when you estimate, round 328.9 to 329 and 7 3/4 to 8. Divide 329 by 8 which is 41.125 which is closest to 40.
#2. 25% because 25% times 80 is 20.
Time = 2*PI* sq root [(length (in metes) / g (9.81 m / sec^2)]
Time = 2 * PI * sq root [(.43) / 9.81]
Time = 2 * PI * sq root [
