A right circular cone is inscribed in a right prism as shown. What is the ratio of the volume of the cone to the volume of the prism? Express your answer as a common fraction in terms of  pi.

And that's the graph.

HI Melody;

Yes, it is a rhombus. It is not different. A rhombus is a special parallelogram and a parallelogram is a special trapezoid.

The diagonals should be perpendicular to each other.

The diagonals of a trapezoid are perpendicular and have lengths 8 and 10. Find the length of the median of the trapezoid.

So, jetzt hat alles geklappt.

So, Ellie

Jetzt erhälst Du alle Lösungen.

Alles ist gerechnet. Aber im Moment klappt es mit dem Hochladen nicht.

Hallo ellie,

warum stellst Du deine Frage nicht auf der deutschen Seite?

Jetzt schicke ich dir erst mal die Ableitungen. Der Rest kommt später.

The bases of trapezoid ABCD are line AB and line CD. We are given that AB < CD, CD = 8, AD = BC = 7, and BD = 9. Find the area of the trapezoid.

A  particular right pyramid has a square base, and each edge of the pyramid is four inches long. What is the volume of the pyramid in cubic inches? Express your answer as a decimal to the nearest hundredth.

1:  An equilateral triangle has a side of length 12 inches. What is the area of the triangle, in square inches? Express your answer in simplest radical form.

2:  In triangle ABC, AB = AC = 5 and BC = 6. Let O be the circumcenter of triangle ABC. Find the area of triangle OBC.

3:  The medians AD, BE, and CF of triangle ABC intersect at the centroid G. The line through G that is parallel to BC intersects AB and AC at M and N, respectively. If the area of triangle ABC is 810, then find the area of triangle AMN.
