Answer:
Step-by-step explanation:
a² + b² = c²
3.6² + b² = 7.4²
b² = 7.4² - 3.6² = 41.8
b = √41.8
The answer is d because the perimeter of 6 by 6 would be 24 and that is the smallest perimeter.
The volume of the pyramid is 13 units³.
<h3>What is the volume of the pyramid?</h3>
A pyramid is a 3-dimensional shape that is made up of a rectangular base and 4 triangular faces. The volume of a pyramid is one-third that of a prism.
Volume of a pyramid = 1/3 x prism
1/3 x 39 = 13

The median average refers to number in the middle of the set. But we need to write it in chronological order.
Now the set becomes 57, 60, 62, 65.
Now find the number in the middle. In this case, it both 60 and 62.
But we need one number.
So, we will take the average of both of them.
60 + 62 = 122
122 / 2 = 61
So, 61 is the median of the set.
