Answer: Option C.

Step-by-step explanation:

You must use the formula for calculate the volume of a cone, which is shown below:

$V_\frac{1}{3}r^2h\pi$

Where r is the radius and h is the height.

Based on the figure attached:

$r=3in\\h=7in$

Substitute these values into the formula for calculate the volume of a cone, then the result is:

$V_\frac{1}{3}(3in)^2(7in)\pi$

$V=65.97in^3$ ≈66in³

A line has a slope of 8 and includes the points (1, z) and (2,8). What is the value of z?

NISA [10]

The value of z is zero

Step-by-step explanation:

The slope is the steepness of the line.

The formula for slope is given by:

$m=\frac{y_2-y_1}{x_2-x_1}\\Here\\(x_1,y_1)\ are\ the\ coordinates\ of\ first\ point\ on\ line\\(x_2,y_2)\ are\ the\ coordinates\ of\ second\ point\ on\ line$

Here

(x1,y1) = (1,z)

(x2,y2) = (2,8)

So,

$m=\frac{y_2-y_1}{x_2-x_1}\\8 = \frac{8-z}{2-1}\\8=\frac{8-z}{1}\\8-8 = -z\\z = 0$

The value of z is zero
