Answer:

height = 20 cm

Step-by-step explanation:

The volume (V) of a cylinder is calculated using the formula

V = πr²h ← r is the radius and h the height

given r = 12 and V = 2880π, then

π × 12²h = 2880π

144πh = 2880π ( divide both sides by 144π )

h = \frac{2880\pi }{144\pi } = 20

An astronomical unit (AU) is the average distance between Earth and the sun. One AU is equal to approximately 150,000,000 km. As
Dimas [21]

Using scientific notation, it is found that the measure of one astronomical unit in kilometers is 1.5 \times 10^8

A number in <em>scientific notation</em> is given by:

a \times 10^b

  • In which a \in [1, 10)
  • To realize the conversion from decimal to scientific notation, b is the number of decimal places the comma moves, being positive if to the left, negative if to the right.  

In this problem, 1 AU = 150,000,000 km.

  • The comma has to move 8 places to the right, hence b = 8

Then, the measure is: 1.5 \times 10^8
