Question

A cylindrical water tank has a diameter of 6 meters and a height of 9 meters. What is the maximum volume of water the tank can hold? (to nearest whole number)

Answer 1

Use the formula for the volume of a cylinder which is V=(pi)r^2h. substitute the values in the equation to make V=(pi)3^2 (9). find the value of 3^2 which is 9. then multiply to get about 254 meters.

Answer 2

Answer: 254 square meter.  

Step-by-step explanation:

Since, the volume of a cylinder,

$V = \pi r^2 h$

Where r is the radius of the cylinder,

h is the height of the cylinder,

Here, r = 6/2 = 3 meter,

h = 9 meter,

Thus, the volume of the given cylindrical water tank

$V = \pi 3^2\times 9$

$V = 3.14\times 81=254.34\approx 254\text{ square meter}$
