radius ( r) = 1 cm
The volume (V) of a sphere is calculated using the formula
V = πr³
here V is given as V = π
Equating gives
V = πr³ =
π
dividing both sides by π, gives
r³ = 1 ( take the cube root of both sides )
r = ∛1 = 1
Answer:
total cost = $ 81
Step-by-step explanation:
It is given that the fixed cost is $ 39
and the cost per minute is $0.07
Let us assume the number of minutes used be x
we have
total cost = cost per minute × number of minutes used + fixed cost
we plug the given values, so we have
we need to find the total cost for 10 hours used
x= 10 hours = 10(60) minutes = 600 minutes
so we have total cost for x= 600 minutes
hence the total cost = $ 81
