Answer:

Step-by-step explanation:

If a sinusoidal function is given in the form y = B Sin x or y = B Cos x, then,

B is called the amplitude of the function. It will define minimum and maximum.

The minimum & maximum of this form of a cos function is B and -B.

The function given is y = 7 Cos x, so the Maximum is 7 and Minimum is -7

Correct answer is B.

The volume of a cone with a diameter of 30 feet and a height of 60 feet is 14130.

<h3>What is the volume of a cone?</h3>

The volume of the cone is given by;

$\rm Volume \ of \ cone=\dfrac{1}{3}\pi r^2h\\\\Where;\ r = radius \ and \ h = height$

The volume of a cone with a diameter of 30 feet and a height of 60 feet.

The radius of the cone is;

$\rm Radius =\dfrac{Diameter}{2}\\\\Radius=\dfrac{30}{2}\\\\Radius=15$

Substitute all the values in the formula

$\rm Volume \ of \ cone=\dfrac{1}{3}\pi r^2h\\\\ Volume \ of \ cone=\dfrac{1}{3}\times 3.14 \times 15^2 \times 60\\\\Volume \ of \ cone=14130$

Hence, the volume of a cone with a diameter of 30 feet and height of 60 feet is 14130.
