I believe that is the correct answer
Answer:
3
Step-by-step explanation:
The formula for circumference is 2×pi × r
We are given the diameter of 2 meters which means the radius is 1 meter. We will use 3.14 for pi.
2 × pi × r =
2 (3.14)(1) =
6.28
The distance around the barbecue pit is
C. 6.28 meters
Given:
Cost of dishwasher : 315 before sales tax
sales tax : 9.22%
Total cost = 315 * 1.0922 = 344.043
Average of 10 uses per week for the next 6 years before replacing it.
There are 52 weeks in a year.
10 uses per week * 52 weeks per year * 6 years = 3120 average uses
cost for water = 0.09 ; cost for electricity = 0.13 ; total cost per use = 0.22
0.22 * 3120 = 686.40 cost of use
purchase cost = 344.043
cost of use = <u>686.40</u>
lifetime cost 1,030.443
