Answer:
The 99th tower contains 9900 blocks.
Step-by-step explanation:
From the question given, we were told that the nth tower is formed by stacking n blocks on top of an n times n square of blocks. This implies that the number of blocks in n tower will be:
n + n²
Now let us use the diagram to validate the idea.
Tower 1:
n = 1
Number of blocks = 1 + 1² = 2
Tower 2:
Number of blocks = 2 + 2² = 6
Tower 3:
Number of blocks = 3 + 3² = 12
Using same idea, we can obtain the number of blocks in the 99th tower as follow:
Tower 99:
n = 99
Number of blocks = 99 + 99² = 9900
Therefore, the 99th tower contains 9900 blocks.
Answer:
You do 1/5 x 125 which equals 25
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
First, get the radius, 2.2*3.14 is 6.908. Then, multiply by 18, 6.908*18 is 124.344.
To do multiplication, what you must do is multiply each number from right to left and add.
For example
60 * 4
4 * 0 = 0
6 * 4 = 24
The result is
240
answer
60 * 4 = 240
A foot is 12 in so a fraction could be 3/12
