Answer:
$16.96
Step-by-step explanation:
Do 3.99 times 2 to get 7.98
And then do 4.49 times 2 to get 8.98
Add the results together to get 16.96
ANSWER
The length of a Diameter is 3.714
EXPLANATION
The circumscribed triangle is shown in the attachment.
We use the cosine ratio to find the altitude of the isosceles triangle.


Altitude =8cos(60°)
Altitude=4cm
Let the upper half of the altitude be y cm.
Then the radius of the circle is (y-4)cm
The upper radius meets the tangent at right angles.
From the smaller right triangle,






y=1.857
The diameter is 2y

=2(1.875)
The length of a Diameter is 3.714
Answer:
22-x
Step-by-step explanation:
you dont know what x is, so you would just do 22-x
Answer:
c squared - a squared = b squared
Step-by-step explanation:
Since a squared + b squared = c squared
With these values it would equal 14 squared - 7 squared = c squared
Then after you find c squared, find the square root of it and there you have go your answer!
