A gemstone is cut in the shape of a triangular pyramid. The area of the base of the pyramid is 42 square millimeters. The
1
height of the pyramid is 4 millimeters. What is the volume of the gemstone? (Recall the formula V = 3 Bh)
56 cubic millimeters
84 cubic millimeters
168 cubic millimeters
336 cubic millimeters

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
