10.8 feet. you add 2 for both sides, and 3.4 for both sides. then add those together.
so, 2+2+3.4+3.4
Formula for volue of cylinder is area time height. Lets find area
A=

diameter=2r
8=2r
r=4
Now substitute r to

A=

Now we have formula
V=

- its the result, so B
Answer:
represents the volume.
Step-by-step explanation:
Given
Length of edge as 's' and height as 'h'
Let 'a' be the area of base
Now, in the other three options the unit is only units and in sah the unit is 
So for any Volume we always have three dimensions that is Length, Breadth and Height.
so 
∴ 
∴ 
That is like 
which is 
Answer:
17
Step-by-step explanation:
an=a1+(n-1)d
a22=-25+21(2)
a22=17
Answer:
x=4200, y=2700
Step-by-step explanation:
let x be first account
y the second
x+y=6900
0.03x+0.08y=342
solve by addition/elimination)
multiply first equation by 0.03
0.03x+0.03y=207 subtract from second
0.03x+0.03y-0.03x-0.08y=207-342
0.05y=135
y=2700, x=4200
