Answer:
4 quarters
10 tenths
Step-by-step explanation:
<h3>Tenths</h3>
<h3>Quarter</h3>
<h3>Whole</h3>
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
∴ There are <u>4</u><u> </u><u>quarters</u> to make a whole
∴ There are <u>10</u><u> </u><u>tenths</u><u> </u>to make a whole
Answer:
(c+3b)/8 = a
Step-by-step explanation:
c= 8a-3b
Add 3b to each side
c+3b= 8a-3b+3b
c+3b = 8a
Divide each side by 8
(c+3b)/8 = 8a/8
(c+3b)/8 = a

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

Side note: The diameter 14 cuts in half to get the radius r = 7
