The volume of a right circular cylinder can be approximated as follows: Volume = πr2h;
where r is the radius of the cylinder and h is the height of the cylinder;
π is a constant that is roughly equal to 3.

Using the simple approximation above, calculate the volume of a right circular cylinder with a radius of 2 meters and a height of 9 meters.

A.
2,916 m3

B.
14 m3

C.
108 m3

D.
324 m3

Answer asap 50 points which of the following distinguishes the soil composition of grassland? 1. the soil supports large trees with thick, long roots, so horizon b needs to be deep enough to sustain larger flora. 2. the soil supports large trees with thick, long roots, so horizon a needs to be deep enough to sustain larger flora. 3. the soil supports small plants and shrubs with short roots, so horizon a needs to be deep enough to sustain smaller flora. 4. the soil supports small plants and shrubs with short roots, so horizon b needs to be deep enough to sustain smaller flora.
