Apentagonal prism is cut by a plane perpendicular to the base. what is the shape of the cross section that is formed?

The shape of the cross section that is formed on this slicing is:

                    A rectangle.

A pentagonal prism is a prism in which the two bases of the prism are in the shape of a pentagon and the five  faces are in shape of rectangles.

Now when the slicing of the prism is done by a plane perpendicular to the base then the cross-section so obtained is similar to the face of the prism.

          Hence, the cross-section so obtained is:

                          Rectangle.

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
