The formula for circumference is 2 x PI x r
Using the circumference we can find the radius:
50.24 = 2 x PI x r
Multiply 2 by PI:
2 x 3.14 = 6.28
50.24 = 6.28 x r
Divide both sides by 6.28:
R = 50.24 / 6.28
R = 8
The radius is 8 units.
Answer:
X = 
, or X = 3.6
Step-by-step explanation:
For this problem we must isolate x
1.03x+3.97x-5=13 | Add 5 to both sides
1.03x+3.97x=18 | Add the x's
5x=18 | Now divide both sides by 5
x=, x=3.6

Answer:
No she will not save enough money for her trip and she needs $122 more for her trip.
Step-by-step explanation:
Deborah requires $74 each day for 13 days trip
Total least amount needed for the trip = 74*13
= $962
Deborah's saving strategy : she saves $84 per month for 10 months
saved amount at the end of the 10th month = 84*10 = $840
840/10 = $84
This clearly shows she is not saving enough money for her trip. She needs $122 more to support the expense of her trip.
Timothy way
84*10= $840 is to be compared with 74*18 = $1332
This method is also not a feasible one for calculating Deborah's expenses of her trip.
