The area of the trapezoid is 87.5 square cm if the parallel side lengths are 10 and 15 cm, the height is 7 cm.
<h3>What is a trapezoid?</h3>It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have a trapezoid ABCD shown in the picture.
As we know the area of the trapezoid is given by:
= (a+b)h/2
= (10+15)(7/2)
= 87.5 square cm
Thus, the area of the trapezoid is 87.5 square cm if the parallel side lengths are 10 and 15 cm, the height is 7 cm.

Let x represent radius of circle.
We have been given that the height of a cylinder is twice the radius of its base. So height of cylinder would be .
Now we will use volume of cylinder formula to our given problem.
, where,
r = Radius of base of cylinder,
h = Height of cylinder.
Upon substituting our given values, we will get:
Therefore, our required volume expression would be .
