Agas tank is filled with 9 liters of gasoline. the dimension of the gas tank is 40cm length, 30cm width, and 20cm height. how high in centimeters will 9 liters of gas fill the gas tank? (1 liter = 1000cm3)

The answer is 7.5 cm.

Step-by-step explanation:

Since 1 liter = 1,000 cm³, then 9 liters of gasoline = 9,000 cm³.

We know that the base area of the gas tank would be covered by the gasoline, but we have to find the height that would be covered. The base area = length of gas tank × width of gas tank = 40 × 30 = 1,200 cm².

Let x be the height covered so that 1,200x (cm² × cm) = 9,000 cm³ (volume of gasoline in the gas tank)

Therefore, the height that 9 liters of gas will fill in the gas tank = x = 9000 cm³ ÷ 1,200 cm² = 7.5 cm.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
