Answer:

  77.03 cm²

Step-by-step explanation:

The appropriate formulas are ...

  CSA = Ch . . . . . curved surface area, C=circumference, h=height

where

  C = πd

or

  d = C/π

__

Here, we have ...

  h = 2d = 2C/π

  C = 11 cm

so the curved surface area is ...

  CSA = (11 cm)(2(11 cm)/π) = 242/π cm² ≈ 77.03 cm²

Savatey [412]
500 = 200 + 20h is our equation.
Subtract 200 from both sides
300 = 20h
Divide by 20
300/20 = 15.
It will take 15 hours to get 500 points.
Hope this helps!
