Cylinder A -
Surface Area:
<em>A = 2πrh + 2πr^2</em>
<em>A = 2 · π · 5 · 7.5 + 2 · π · 25 ≈ 392.69908</em>
<em>A = </em>392.7 cm^2
Volume:
<em>V = πr^2h</em>
<em>V = π · 25 · 7.5 ≈ 589.04862</em>
<em>V = </em>589 cm^3
Cylinder B -
Surface Area:
<em>A = 2πrh + 2πr^2</em>
<em>A = 2 · π · 3.5 · 5 + 2 · π · 12.25 ≈ 186.92476</em>
<em>A = </em>186.9 cm^2
Volume:
<em>V = πr^2h</em>
<em>V = π · 12.25 · 5 ≈ 192.42255</em>
<em>V = </em>192.4 cm^3
Answer:
Part 1) The draw in the attached figure
Part 2) 
and 
Step-by-step explanation:
Part 1) Draw and label the triangle.
we know that
The isosceles triangle has two equal sides and two equal interior angles
In this problem we have the isosceles triangle ABC
so
AB=AC
∠B=∠C
The draw of the isosceles triangle ABC in the attached figure
Part 2) Write two equivalent expressions for its length of the perimeter
Remember that
The perimeter of any triangle is the sum of its three length sides
In this problem
The perimeter of triangle ABC is equal to
substitute the given values
Combine like terms
Write other equivalent expression
Factor the number 7
Answer:
Order the set of values
9, 10, 11, 12, 14, 20
<h2>Median:</h2>
Middle Value
n = number of values
if n is odd, the median is at position n/2
if n is even, the median is between position n/2 and n/2 + 1
n = 6
6 is even, so the median is between position 6/2 and 6/2 + 1
the median is between 11 and 12
(11 + 12)/2
23/2
11.5
<h2>Mean </h2>
9 + 10 + 11 + 12 + 14 + 20 = 76/6
= 12.666...
= 12.7 to the nearest tenth.
