2 answers:
The width of rectangular prism is 4.5 inches
<em><u>Solution:</u></em>
Given that volume, V, of a rectangular prism is determined using the formula:
v = lwh
Where is the length, w is the width, and h is the height of the prism
To find: width of rectangular prism
From given question,
v = 138.24 cubic inches
h = 9.6 inches
l = 3.2 inches
Substituting the values in formula, we get
Thus the width of rectangular prism is 4.5 inches

Answer:
π/2 : 1 or π : 2
Step-by-step explanation:
In the attachments I have a picture of a square inscribed in a circle.
Call the side of the square a. Therefore, the area of the square is a^2.
We can also see that the diagonal of the square is the circle's diameter.
Using the Pythagorean Theorem we find that the diagonal/diameter of the circle is a√2. Thus the radius is that divided by 2, which is (a√2)/2.
We also know that the formula for a circle's area is πr^2, so the area of the circle is π((a√2)/2)^2 --> π(a^2)(2)/4 --> π(a^2)/2.
Hence the ratio of the circle to the square is π(a^2)/2 to a^2 which is π/2 to 1 or π to 2.
