The water level at Lake Penny changed −1 1/10 in. this year. Next year, it is predicted to change another −1 2/5 in.

ziro4ka [17]

Answer:

$- 2\frac{1}{2}$ inches

Step-by-step explanation:

The water level at Lake Penny changed $- 1\frac{1}{10} = - 1.1$ inches

Again, in the next year, it is predicted to change another $- 1\frac{2}{5} = - 1.4$ inches

Therefore, the total change that will likely occur in 2 years is (- 1.1 - 1.4 ) = - 2.5 inches = $- 2\frac{1}{2}$ inches. (Answer)

vivado [14]

Answer:

B: 28pi m^3

Step-by-step explanation:

r = 4/2 = 2 m

h = 7 m

Volume of cylinder
