V = Volume of the spherical tank = 11000 ft³
d = diameter of the sphere = ?
Volume of water in the tank is same as the volume of sphere
The formula for Volume of spherical tank is given as
V = (π/6) d³
so
d³ = 6V/π
d = ∛(6V/π)
inserting the values given above
d = ∛(6(11000)/3.14)
d = ∛(66000/3.14)
d = ∛(21019.11)
d = 27.6 ft

Answer:
70
Step-by-step explanation:
Answer:
3 toppings for a total of $6.50
Step-by-step explanation:
Based on the information provided we can calculate the cost of a yogurt using the following equations for both Froyo Express (F) and The Big Chill (B) , where the variable x represents the number of toppings...
F = 5.75 + 0.25x
B = 2.75 + 1.25x
Now that we have both equations we can simply make one equal to the other and solve for x in order to calculate at what number of toppings the prices will be the same...
5.75 + 0.25x = 2.75 + 1.25x ... subtract 2.75 and 0.25x on both sides
3 = 1x ... divide both sides by 1
3 = x
Finally, we can see that at 3 toppings the total cost of both stores will be the same at $6.50
