Answer:

[tex]\sf 113 \ km^3[/tex]

Step-by-step explanation:

Volume of cylinder:

Find radius from the diameter.

        r = 12 ÷ 2

       r = 6 km

      h = 1 km

Substitute  r and h in the below formula,

      [tex]\boxed{\text{\bf Volume of cylinder = $\bf \pi r^2h$}}[/tex]

                                           [tex]\sf = 3.14*6*6*1\\\\= 113..04 \\\\ =113 \ km^3[/tex]

Hello !

Answer:

[tex]\Large \boxed{\sf V\approx 113.0\ km^3}[/tex]

Step-by-step explanation:

The volume of a cylinder is given by [tex]\sf V=\pi\times r^2\times h[/tex] where r is the radius and h is the heigth.

Given :

  • d = 12km
  • r = d/2 = 6km
  • h = 1km

Let's replace r and h with their values in the prevous formula :

[tex]\sf V=\pi\times6^2\times1\\V\approx 3.14\times 36\\\boxed{\sf V\approx 113.0\ km^3}[/tex]

Have a nice day ;)
