<h3>
Answer: 282.6 square units</h3>
====================================================
Work Shown:
r = 3 is the radius of the circular base
h = 12 is the height of the cylinder
pi = 3.14 approximately
SA = surface area of the cylinder
SA = 2pi*r^2 + 2pi*r*h
SA = 2*3.14*3^2 + 2*3.14*3*12
SA = 282.6
Answer:
1/2 mile
Step-by-step explanation:
3/8+1/8=4/8 or 1/2 simplified
1-1/2=1/2
same has to walk 1/2 mile more to walk his dog a full mile
9/16 + 1/4
9+4/16
13/16
Alternative form
0.8125
You draw a number line do +100 on the line then do +100 +100 +50 +8 then you add them up
