Answer:
The answer is 15.71
Explanation:
All you have to do is multiply Pie or 3.14 with 5 from the sphere. 3.14 x 5 = 15.7. If you use the Pie symbol when multiplying you'll get this answer -> 15.70796327. But I recommend using the pie symbol and just rounding it off. When rounding 15.70796327 to the hundredth place, do you know the saying 5 & up moves up and 4 & below stays??? Will it's the same thing here. 7 in 15.707 will move the 0 to a 1 instead of a 0.
