Answer:

74.33

Step-by-step explanation:

We need to figure out the surface area. The formula for surface area is A=2πrh+2πr2

We substitute r with the radius of this cylinder and the h represents the height of this cylinder. The height we can find because we just add the diameters of the tennis balls. So 2.6*3 = 7.8. Then we get the radius, which will just be the radius of a sphere, so 1.3. Then we plug them into the formula, giving us 74.33

yaroslaw [1]

Answer:

10.4 miles

Step-by-step explanation:

Write an equation for the total cost paid as a function of the # of miles driven:

L(x) = $6.75 + ($3.20/mile)x

and set this equal to $40.03 to determine the # of miles Lupita rode:

L(x) = $6.75 + ($3.20/mile)x = $40.03

Isolate the x term by subtracting $6.75 from both sides:

($3.20/mile)x = $40.03 - $6.75 = $33.28

Finally, divide both sides by  ($3.20/mile):

x = $33.28 /  ($3.20/mile)

  =  10.4 miles

Lupita rode 10.4 miles in the taxi.
