Answer
Step-by-step explanation:
Radius is always half of the diameter so, 
is equal to 
.
The Formula for Circumference is 
Since we found out the radius, we need to basically substitute (or insert) it into the radius spot so the next step will be: 
Then we multiply (2)(1.25) to get an answer of 2.5 (which we already know)
So our answer is going to be
Hope this helped and answers your question! Have a great rest of your day/night!
So you have a diagram or picture of the triangle?
Anyways...
Answer: 36
Explanation:
3:5:7 is the ratio of the triangle's angles
The sum of all angles = 180 degrees.
3 + 5 + 7 = 15
Lets assume 'a' is the smallest angle with the ratio of 3
b is the second largest with a ratio of 5
And c is the largest angle with the ratio of 7
In other words:
a + b + c = 180
For 15 to get to 180 => 180 ÷ 15 = 12
So 15 × 12 = 180
So for 3 to get to a => 3 × 12 = 36
Thus the smallest angle is 36 degrees
because
is a set with the element 0, so it's not the empty set, while
is the empty set.

Answer:
The volume of the pyramid is 867 inch^3
Step-by-step explanation:
Here in this question, we are interested in calculating the volume of a square based pyramid.
Mathematically, we can use the formula below to calculate the volume V of a square based pyramid.
V = a^2h/3
where a represents the length of the side of the square and h is the height of the pyramid
From the question, the length of the side of the square is 17 in while the height is 9 in
Plugging these values, we have ;
V = (17^2 * 9)/3 = 17^2 * 3 = 867 cubic inch
