The cost is the number of videos (V) times the cost of a video, plus the monthly fee.
C=2.25V+5
Answer:
Step-by-step explanation:
circumference = 2πr
2πr = 30π inches

Area = πr² = π*15*15 = 225π square inches
We have 1.2 × 10^(-4) x 6.25 × 10^(-5 ) = 7,5 x 10^(-9) = 75 x 10^(-10) square kilometers.
