Answer:
56 m
Step-by-step explanation:
5 on the top side short
5+7 on the left side
5+11 on the bottom side
7 on the bottom right side
11 on the long top side
5 on the top right side
so 5+(5+7)+(5+11)+7+11+5
Answer:
C) $826.82 to $873.18.
Step-by-step explanation:
Sample mean (M) = $850
Standard deviation (s) = $54
sample size (n) = 36
Z for 99% confidence interval (Z) = 2.576
The confidence interval is determined by the following relationship:
Applying the given values, the lower (L) and upper (U) values are:
The answer is C) $826.82 to $873.18.
Answer:
Part 1) The shapes that make up the figure are two hemispheres and a cylinder
Part 2) see the explanation
Part 3) see the explanation
Part 4)
Step-by-step explanation:
Part 1) Define the shapes that make up the figure.
we know that
The shapes that make up the figure are two hemispheres and a horizontal cylinder
Part 2) Identify the volume formula(s) that will be be used for each shape in number 1.
we know that
The volume of a hemisphere is equal to
where
r is the radius of the hemisphere
The volume of a cylinder is equal to
where
r is the radius of the base of cylinder
h is the height or length of the cylinder
Part 3) Find the volume for each individual shape.
step 1
Find the volume of a hemisphere
we have
substitute
step 2
Find the volume of the horizontal cylinder
we have
substitute
Part 4) Find the composite volume of the original figure
The volume of the composite figure is equal to the volume of two hemisphere plus the volume of the cylinder
so
Convert to mixed number
We don't have to stress too much over the details, which are a little muddled here. When we scale the linear dimension by a factor of <em>f </em>we scale areas by a factor of .
It's not totally clear from the question but let's say A is on the inner circle of radius <em>r</em> and B on the outer circle of radius <em>R.</em> The linear dimensions are scaled by the ratio so the area is scaled by
