Two trains are traveling at constant speeds on different tracks. Train A:
0 12.5
100
distance traveled (meters)
elapsed time (seconds)
0
Train B:
100
distance traveled (meters)
clapsed time (seconds)
4
Train A is traveling 12.5 meters per second. What speed is Train B traveling?
meters per second,

ok

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a
