Answer: 117.45 ft²
Step-by-step explanation:
There is a general formula for calculate the surface area of a regular pyramid. This is:
Where p is the perimeter of the base, l is the slant height and B is the area of the base.
The perimeter is:
The base is an hexagon, therefore you can find the area by using the formula for the area of a regular polygon:
The slant height can be calculated with Pythagorean theorem. The hypotenuse is the slant height and the other legs are 6ft and:
Then:
Then, the surface area is:
Answer:
It is a Right angle triangle ,
So, Apply Pythagoras Theorem ,

If ola wants to receive $30 in cash, the amount she should enter on the currency line is; $172.75
<h3>How to find the currency amount?</h3>
She wants to deposit the checks and has two of them with different amounts. Thus, we add them to get the total deposit amount.
Total deposit checks = $32.75 + $41.50
Total deposit checks = $74.25
9 ones = $9
3 fives = $15
2 tens = $20
4 twenties = $80
32 nickels = $1.6
4 dimes = $0.4
10 quarters = $2.5
Add up these amounts gives a total of $128.5
Deposit means to add to her account. Adding up these two totals gives;
Total = $128.50 + $74.25 = $202.75
She wants to receive $30 in cash. This means that $10 will be withdrawn; $202.75 - $30 = $172.75
If she puts $172.75 in the total line to make the deposit.
