Find the volume of a road construction marker, a cone with height 2 ft and base radius 1/5 ft. Use 3.14 as an approximation for π.The volume of the cone is __. (ft^2, ft^3, ft)(Simplify your answer. Type an integer or decimal rounded go the nearest hundredth as needed.)

Respuesta :

Remember that

The volume of a cone is equal to

[tex]V=\frac{1}{3}\cdot\pi\cdot r^2\cdot h[/tex]

we have

r=1/5 ft

pi=3.14

h=2 ft

substitute given values

[tex]\begin{gathered} V=\frac{1}{3}\cdot3.14\cdot(\frac{1}{5})^2\cdot2 \\ V=0.08\text{ ft3} \end{gathered}[/tex]

the answer is 0.08 ft^3
