What is this solid figure?

cylinder

Step-by-step explanation :A cylinder is a solid composed of two congruent circles in parallel planes, their interiors and all the line segments parallel to the segment containing the centers of both circles with endpoints on the circular regions. The circles and their interiors are the bases . The radius of the cylinder is the radius of a base.

Cylinder

Step-by-step explanation:

STEP ONE:

Identify base. It is a circle.

STEP TWO:

Identify the top of the figure. If it is the same as the lower base, then it is a cylinder.

So, this shape is a cylinder.

for b its (t) and c its (d)

step-by-step explanation:

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
