Question

keep going! calculate the volume of each cylinder. use 3.14 for π. remember that the diameter of a circle is twice its radius.
16 mm
4 mm
24 ft.
14 ft.
v≈
v≈

Explanation:

For the first cylinder (in mm):

Step1: Find the radius

The diameter is 16 mm, so the radius \( r=\frac{16}{2} = 8\) mm.

Step2: Use the cylinder volume formula \( V=\pi r^{2}h \)

Here, \( \pi = 3.14 \), \( r = 8 \) mm, \( h = 4 \) mm.
\( V=3.14\times8^{2}\times4 \)
\( = 3.14\times64\times4 \)
\( = 200.96\times4 \)
\( = 803.84 \) cubic millimeters.

For the second cylinder (in ft):

Step1: Find the radius

The diameter is 24 ft, so the radius \( r=\frac{24}{2}=12 \) ft.

Step2: Use the cylinder volume formula \( V = \pi r^{2}h \)

Here, \( \pi=3.14 \), \( r = 12 \) ft, \( h = 14 \) ft.
\( V=3.14\times12^{2}\times14 \)
\( = 3.14\times144\times14 \)
\( = 452.16\times14 \)
\( = 6330.24 \) cubic feet.

Answer:

For the first cylinder: \( V\approx\boldsymbol{803.84} \) cubic millimeters.
For the second cylinder: \( V\approx\boldsymbol{6330.24} \) cubic feet.
