The area of a sector of a circle with a radius of 4 centimeters is 2.512 square centimeters. the estimated value of π is 3.14.
the measure of the angle defining the sector is what in degrees

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie

The cross-sectional areas of a right triangular prism and a right cylinder are congruent. the right triangular prism has a height of 6 units, and the right cylinder has a height of 6 units. which conclusion can be made from the given information? the volume of the triangular prism is half the volume of the cylinder. the volume of the triangular prism is twice the volume of the cylinder. the volume of the triangular prism is equal to the volume of the cylinder. the volume of the triangular prism is not equal to the volume of the cylinder.

Which is the value of this expression when p=3 and q=-9
