If the radius of a cylinder is doubled and the height is tripled, what happens to the volume? A) It is multiplied by 6. Eliminat
lana66690 [7]
A. Imagine the circle has a radius of 3 and height of 9. 3 x 9 = 27/3 is 9. If radius is doubled that’s 6 and height is tripled would make it 27. So 6 x 27 is 162 divided by 3 is 54 and 9 x 6 is 54

Phoenix [80]

(1) 34.8 liters

(2) $63.55

Solution:

(1) There is a mistake in question. It is 42 liters.

Total gasoline a car can hold = 42 liters

Liters of gasoline filled in beginning of the week = 35.8

Liters of gasoline used during the week = 28.6

Remaining liters of gasoline in the tank = 35.8 – 28.6

                                                                  = 7.2 liters

Quantity of gasoline need to buy to fill the tank completely

                               = Total capacity – Remaining gas in the tank

                               = 42 liters – 7.2 liters

                               = 34.8 liters

Hence Alberto need to buy 34.8 liters of gasoline to fill the tank.

Option B is the correct answer.

(2)

Shamika earns in first week = $25.75

Shamika earns in next week = $37.80

Total money Shamika have = First week earning + Second week earning

                                              = $25.75 + $37.80

                                              = $63.55

Don't add or subtract spending money, because the question is how much she have from these two weeks.

Hence Shamika have $63.55 from these two weeks.
