Answer:
No
Step-by-step explanation:
We can check this using the Pythagorean Theorem, .
First, we can plug our two smaller sides in for a and b, and the largest side in for c.,
Next, we can check the left side of the equation, which we find to be:
Then, we can add these products and achieve the result of 425
Finally, we can solve the right side of the equation, which equals 625
As 425 ≠ 625, this equation fails the Pythagorean Theorem, and is therefor false.

Answer:
The volume of the given pyramid is 300 cm³
Step-by-step explanation:
The volume of a pyramid, , is given as follows;
The height of the pyramid = 12 cm
The side length of the square base of the pyramid = 5 cm
The base area of the pyramid polyhedron with square base = 5 cm × 5 cm = 25 cm²
Therefore, by substitution, we have;
The volume of the given pyramid, V = 300 cm³.
The coordinates of centroid of given triangle are: (3,3)
Step-by-step explanation:
Given
