This is the formula for the surface area of a cylinder including the ends, like the total surface area of a can of peas.
S = 2·π·r² + 2·π·r · H
Divide each side by 2·π·r :
S/2·π·r = r + H
Subtract r from each side :
H = (S/2·π·r) - r
or
H = (S - 2·π·r²) / (2·π·r)
The answer is g) y= 27.6 and x=11
1.5y=41.4
1.5y/1.5=41.4/1.5
y=27.6
1/2 b-39=101
+39 +39
1/2 b= 140
2(1/2) b= 140(2)
b=280
The answer is B.
When you set up a ratio of all the corresponding sides, the ratios all equal 2:1
6(x + y) + (x - y)
<em>use distributive property</em>
= 6x + 6y + x - y
<em>combine like terms</em>
= (6x + x) + (6y - y)
<h3>= 7x + 6y</h3>
