Answer:

Step-by-step explanation:
The surface area of a cylinder is equal to

Solve for h
That means ----> isolate the variable h
subtract 2πr² both sides

Divide by 2πr both sides

Rewrite

Simplify

To find the circumference, multiply the diameter by pi.
3.14 x 10 = 31.4 inches
Answer:
Hey there!
x+x+1/4+x+2/4
3x+0.75=6.75
3x=6
x=2
The lines are 2, 2 1/4, and 2 2/4.
Let me know if this helps :)
hour hands:
the hour hand is located at position 0.
minute hands:
the minute hand is located in position 6.
The angle of each position of the watch is:
360 * (1/12) = 30
The difference of position between the hands is:
6-0 = 6
Therefore the angle between hands is:
(6) * (30) = 180 degrees:
Answer:
there are 180 degrees in the smaller angle formed by the minute and hour hands on a clock at 12:30
it should be rounded to 30.1
