Circumference = πD
30π = πD
D = 30 inches
Answer: 30 inches

Answer:
0.2 - 0.3 pounds
Step-by-step explanation:
Well because I dont know much information about the weight and background of the pencils. My answer may not be correct. But the average weight would be around 0.2 - 0.3 lbs.
Exact Surface Area = 378pi
Approximate Surface Area = 1186.92
The approximate surface area uses pi = 3.14
The units are cm^2 or "square cm".
=========================================================
Work Shown:
SA = surface area of cylinder
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*pi*7^2 + 2*pi*7*20
SA = 2*pi*49 + 2*pi*140
SA = 2*49*pi + 2*140*pi
SA = 98pi + 280pi
SA = 378pi ..... exact surface area
SA = 378*3.14
SA = 1186.92 ..... approximate surface area
