theta=-55 degree

</span><span>the theta angle could belong to the third or fourth quadrant

</span><span>case a) theta belong to the IV quadrant
so
theta=360-55-----> theta=305</span>°

I need to know what the volume of the cone in cubic inches please
ivolga24 [154]

Answer:

V = 118 in³

Step-by-step explanation:

The volume of a cone of radius r and height h is V = (1/3)(π)(r^2)(h).

In this case, the volume is V = (1/3)π(3 in)^2·(6 in), or π(18 in³)

Using 3.14 as the approximate value of π, we get V = 118 in³

The inequality would be x > 453 because any year after he died would be more than the year he died.
