Question

What is the answer so I can answer it on my side of the phone

Answer 1

Answer:

C. 134.04 $cm^{2}$

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 = $\pi$ x $radius^{2}$

The radius of the base is 4cm

=> Area of base = $\pi$ x 4^2 = 3.14 x 16 = 16$\pi$ $cm^{2}$

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$\pi$ x 8 = 134.04 $cm^{2}$

So the answer is C
