If you would like to know how much did Danielle spend on a long distance, you can calculate this using the following steps:
C = $77.70 - $29.95 for a basic cell phone rate - $5.95 for voice mail - $2.95 for text messaging = 77.70 - 29.95 - 5.95 - 2.95 = $38.85 on a long distance
Danielle spent $38.85 on a long distance.
The first one is 1.12867 because you need to set it up like this.
4=3.14(x)squared
4/3.14=x(squared)
x=1.12867
The second one is done simply by multiplying it out.
A=3.14(3x)squared
A=3.14(9x[squared])
A=28.26x[squared] -The squared is referring to the x.
