Jason found a steel wire in a form of a circular ring that had a circumference 25.12 inches. What would be the diameter of the w
2 answers:
<u>Answer:</u>
8 inches
<u>Step-by-step explanation:</u>
The circumference of a circular ring of the steel wire = 25.12 cm
To find the diameter of the circular ring, we will first find the radius of the circular ring, using the circumference, and then multiply it by 2.
We know that:
<em>Circumference = </em>
25.12 = 2 x 3.14 x r
r = 25.12 / (2 x 3.14)
r = 4 inches
Therefore, the diameter of the circular ring will be 2 x 4 = 8 inches.

Given:
Max's house has two steps on the front porch.
Size of each step is the same.
To find:
The total vertical distance covered by the two steps.
Solution:
From the given figure, it is clear that,
Base length of each step = 6 in
Hypotenuse = 10 in
Let h be the vertical height of each step.
Using Pythagoras theorem, the vertical height of one step is
Taking square root on both sides.
Height cannot be negative. So, h = 8 in.
Now,
Vertical height of 2 steps =
=
So, the total vertical distance covered by the two steps is 16 in.
Therefore, the correct option is A.
