V=\cfrac{\pi r^2 h}{3}\qquad 
\begin{cases}
r=radius\\
h=height\\
----------\\
r=6\\
h=11
\end{cases}\implies V=\cfrac{\pi \cdot 6^2\cdot 11}{3}$

Estimate 63.730+ 32.73 by first rounding each number to the nearest whole number

Shalnov [3]

Answer:

Step-by-step explanation:

Round each number to the nearest whole number (the digit directly left to the decimal point.) Note that if the digit to the right of the decimal point is 5 or greater, round up; if it is 4 or lower, round down:

63.730 rounded to the nearest one is 64.

32.73 rounded to the nearest one is 33.

Add:

64 + 33 = 97

97 is your answer.
