Answer:
C. 134.04 [tex]cm^{2}[/tex]
Step-by-step explanation:
The formula to calculate the volume of the cone is:
+) Volume of a cone = 1/3 x Area of base x Height
The base of the cone is a circle, so that the formula to calculate the are of the base is: Area of base = [tex]\pi[/tex] x [tex]radius^{2}[/tex]
The radius of the base is 4cm
=> Area of base = [tex]\pi[/tex] x 4^2 = 3.14 x 16 = 16[tex]\pi[/tex] [tex]cm^{2}[/tex]
The height of the cone is given equal to 8 cm
So the volume of the cone is:
+) Volume of a cone = 1/3 x Area of base x Height = 1/3 x 16[tex]\pi[/tex] x 8 = 134.04 [tex]cm^{2}[/tex]
So the answer is C
