99 litres of gasoline oil is poured into a cylindrical drum of 60cm in diameter. How deep is the oil in the drum? ​
ICE Princess25 [194]

Answer:

  35 cm

Step-by-step explanation:

The volume of a cylinder is given by ...

  V = πr²h

We want to find h for the given volume and diameter. First, we must convert the given values to compatible units.

  1 L = 1000 cm³, so 99 L = 99,000 cm³

  60 cm diameter = 2 × 30 cm radius

So, we have ...

  99,000 cm³ = π(30 cm)²h

  99,000/(900π) cm = h ≈ 35.01 cm

The oil is 35 cm deep in the drum.

PLZ HELP!!! CORRECT ANSWER ONLY PLEASE<br><br> What is the value of x?
irina1246 [14]

Answer:

  x = 98 mm

Step-by-step explanation:

The angle bisector YT divides the triangle into proportional segments:

  VY/VT = KY/KT

Filling in the numbers and multiplying by VT, we have ...

  VY/57 = 68/129.2

  VY = 57·68/129.2 = 30

Then we can find x from ...

  x = VY + YK = 30 +68 = 98 . . . mm

The value of x is 98 mm.
