Question

A cylindrical well is 25 meters deep and has a diameter of 1.8 meters. Approximately how many cubic meters of soil were dug out to make the well? (Use π = 3.14.) (5 points)

a
10.17 cubic meters

b
21.19 cubic meters

c
63.59 cubic meters

d
70.65 cubic meters

Answer 1

Answer:

(c) 63.59 cubic meters.

Step-by-step explanation:

Volume of the cylinder = cubic meters of soil dug out

Volume of a cylinder = π$r^{2}$h

Volume = $3.14$ * $\frac{18}{20}$ * $\frac{18}{20}$ * $25$

             = $\frac{314}{100}$ * $\frac{18}{20}$ * $\frac{18}{20}$ * $25$

             = $\frac{25434}{400}$

             = $\frac{25434}{4} * \frac{1}{100}$

             = $6358.5 * \frac{1}{100}$

             = 63.585 $m^{3}$

We can round off 63.585 $m^{3}$ to 2 decimal places.

∴ Total cubic meters of soil dug out is (c) 63.59 $m^{3}$.
