Question

3 8. A toy box is shaped like a cylinder. The diameter is 4 feet and the height of the container is 2 feet. Which measurement is closest to the volume of the toy box in cubic feet? A. 153.5 B. 12.22 C. 10.49 D. 38.37

Answer 1

Step 1

Write out the formula for volume of cylinder

`\begin{gathered} \text{Volume of cylinder = }\pi r^2h \\ \end{gathered}`

r = radius

h = height

pi = 3.142

Step 2

write out the parameters

diameter = 4 feet

radius = diameter/2 = 4/2 = 2 feet

height = 2 feet

Step 3

input values in the foemula

`\begin{gathered} \text{Volume of a cylinder = }\pi r^2h \\ =\text{ 3.142 }*2^2\text{ }*\text{ 2} \\ =\text{ 3.142 x 4 x 2} \\ =\text{ 25.136} \end{gathered}`
