a Find the volume of the specified cone. Use 3.14 for x, and round your answer to the nearest whole number. Radius = 4 in., Height = 9 in. 301 cu. in. b. 226 cu. in. 75 cu. in. d. 151 cu. in. Please select the best answer from the choices provided ΟΑ OB с OD

Answer 1

$\begin{gathered} \text{Volume of a cone = }\frac{1}{3}\times\pi\times r^2\times h \\ r=\text{ 4in} \\ h\text{ = 9in} \\ \pi=\text{ 3.14} \end{gathered}$$V\text{ = }\frac{1}{3}\times3.14\times4^2\times9$$\begin{gathered} V\text{ = }\frac{452.16}{3} \\ V=150.72inch^3 \end{gathered}$

volume of cone approximately is 151 cubic inch
