Part a) Find the expression that gives the perimeter of ∆XYZ
we know that
Perimeter of triangle ABC is equal to
In this problem ∆ABC and ∆XYZ are similar triangles
the scale factor is equal to r
so
therefore
the answer Part a) is
The expression that gives the perimeter of ∆XYZ is 
Part b) Find the expression that gives the area of ∆XYZ
we know that
therefore
the answer Part b) is
The expression that gives the Area of ∆XYZ is 
14/x = 1/2
Cross multiply, which is: a/b = c/d ⇒ ad = bc
After cross multiplying, we get:
x = 2(14)
x = 28
Your final answer is C. 28<span>.</span>
Step-by-step explanation:
The volume of a cylinder can be found with the equation
<em><u>
</u></em>
So, plug in the values. The diameter of the circle is 10m, which means that the radius is 5m. The height of the cylinder is 13m.
V = π (5)^2 (13)
<u>V = 325π m^3</u>
Answer:
D. 325π m^3
Answer: 10
Step-by-step explanation:
You use the distance formula to find the distance.
Find the difference between the two x variables (8), and the distance between the two y variables (6). Square both differences, (64 and 36), add them (100) and find the square root of the sum, 100.
