What is the approximate volume of this cone? 3.14 as your approximation for π

Enter your answer as a whole number, like this: 42

Estimate the sum in two different ways:

A) By rounding off to the highest place value (hundreds):

 368 = 400  (3 hundreds is the highest place value)

 231 = 200 (2 hundreds is the highest place value)

 400 + 200 = 600

B) By rounding off to the second highest place value (tens):

   368 = 370

   231 = 230

   370 + 230 = 600

Hope this helps!
