Answer: 3053.63 sq. cm.

Step-by-step explanation:

Volume = 4/3π x r^3

= 4/3 x π x 9^3

= 4/3 x π x 729

= (4π x 729) / 3

= 4π x 243

= 972π

Austin is 69 years younger than Jamie. 3 years ago, Jamie's age was 4 times Austin's age. How old is Austin now?
matrenka [14]

Answer: 26 years old

Step-by-step explanation:

  1. Create an equation with Austin as x and Jamie as x+69 (I just like workin with addition signs more)= 4(x-3)= x+69-3
  2. Simplify the equations --> 4x-12=x+66
  3. Solve the equation: 3x-12=66 --> 3x=78 --> x=26

This is the same as other age problems, just with the extra step of distributing the multiplication.
