Question

a company is filling a cylindrical storage tank with a height of 12 m and a radius of 6 m. what is the approximate volume of the tank using π ≈ 3.14?
a. 678.24 m³
b. 1356.48 m³
c. 1440.2 m³
d. 1357.92 m³

the shape of the base of a cylinder is:
a. rectangle
b. square
c. circle
d. triangle

Explanation:

Step1: Recall volume formula for cylinder

The volume formula for a cylinder is $V=\pi r^{2}h$.

Step2: Substitute given values

Given $r = 6$ m, $h=12$ m and $\pi\approx3.14$. Substitute into the formula: $V\approx3.14\times6^{2}\times12$.

Step3: Calculate the result

First, $6^{2}=36$. Then $3.14\times36\times12 = 3.14\times432=1356.48$ $m^{3}$.

For the second - part:
The base of a cylinder is a circle.

Answer:

1. b. $1356.48$ $m^{3}$
2. c. Circle
