These cylinders are similar. Find the surface area of the smaller cylinder. Round to the
nearest tenth.
5 cm
3 cm
Surface Area = [ ? ] cm2
Surface Area = 236 cm2

Surface Area = 6.28 x 5.223 x 3 + 6.28 x 10.446 = 164 cm^2Step-by-step explanation:

A=2πrh+2πr2

When we divide 245 by 1.5 we find 164cm^2

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

9 x 8 divided by (5-3)=36
