What is the total surface area of the following cylinder?

a. 1,017.36 cm2
b. 791.28 cm2
c. 2,034.72 cm2
d. 395.64 cm2

The correct answer is opyion B,

Step-by-step explanation:

Surface area of cylinder

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
