Sorry if it's wrong, I tried
8x + 5(-4x) = 24
8x - 20x = 24
-12x = 24
x = -2
y = -4(-2)
y = 8
Therefore, the point of intersection is (-2,8).
The Volume of cylinder is 3770 cubic millimeters
But, the correct option is not available in options given.
Step-by-step explanation:
Height of cylinder = 3mm
Diameter of cylinder = 40mm
Volume of cylinder = ?
The formula used to find Volume of cylinder is:

Putting values in the formula:
Since we need radius,
radius = diameter/2
radius = 40/2
radius = 20 mm
So,
