Which of the following is a property of a right circular cylinder? A. Its surface area is equal to the lateral surface area plus πr2. B. Its bases are parallel but not congruent. C. Its volume is four times the area of its base. D. Its lateral surface area is equal to the product of its perpendicular height and the circumference of its base.

D.

Step-by-step explanation:

The lateral surface area measures the area of the outside of the 3D shape. *Doesn't include the bases.

Since the measure of the outside of a cylinder is essentially a RECTANGLE, the formula for area is length x width. The length here would be the height, the width would be the circumference.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
