A cylinder has a base radius of 4m and a height of 6m. What is its volume in cubic m,

BlackZzzverrR [31]

Answer:

301.4

Step-by-step explanation:

Volume of a cylinder=pi* $r^{2}$ *h. Assuming you want 3.14 for pi, we can substitue the 4m for r, 6 for h and 3.14 for pi.

V=3.14* $4^{2}$ *6

V=301.44

Since you want to round to nearest tenths, the answer is 301.4
