Answer:
Step-by-step explanation:
The volume of a cylinder is:
where 
is the radius and 
is the height.
The height is 4 inches greater that the radius, so:
Substituting this in the formula for volume:
the volume is 
thus:
Dividing everything between pi:
We can see that the solution for this is 
since 
We have the radius, now we find the height:
Answer:
V=M/D
Step-by-step explanation:
D=M/V
multiply both sides by V
divide both sides by d
V=M/D
Answer:
square has four sides. and all four sides are equal.
so if side = x units
perimeter = x + x + x + x = 4x
Perimeter = 4 x length of one side
Answer:
5/8 feet
Step-by-step explanation:
3/8 ÷ 3/5
3/8 x 5/3 = 15/24 = 5/8
CHECK YOUR WORK:
5/8 x 3/5 = 15/40 = 3/8
Answer: Let us assume that our income is $X.
In the first case:
1) We received a raise and our income increased to 135% of its previous amount.
"increased to" denotes that we will multiply our original income by the percentage given.
Therefore our income would be = $X * 1.35 = $1.35
X
In the second case:
2) We received a raise and our income increased by 135%.
"increased by" denotes that we have to add the given percentage of our income to our original income.
<em><u>Therefore our income would be $X + $X*1.35= $2.35X</u></em>
