Answer:

38.1%

Step-by-step explanation:

Increase = 29 - 21 = 8

Increase % = increase/original x 100

                  =  8/21 x 100

                  = 0.381 x 100

                  = 38.1%

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
