Answer: C)
Step-by-step explanation:
First we need to calculate the area of the square base.
This is 7*7 which equals 49 cm squared.
Plug this value into the formula of a square pyramid which will be , now plug in the h, which is 9 cm.
Now solve.
V = 147 cubic cm.

<u>Arithmetic Sequences </u>
The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
The sum of the n terms of an arithmetic sequence is given by:
We are given the first two terms of the sequence:
a1=5, a2=8. The common difference is:
r = 8 - 5 = 3
Thus the general term of the sequence is:
The formula for the sum is:
