Acylindrical trash can is 30 inches high and has a base radius of 7 inches. what is the outside surface area of this trash can, including the top of the lid?

The answer to your question is: A = 1627.35 in²

Step-by-step explanation:

Data

height = 30 in

radius = 7 in

A = ?

Lateral area

  A = 2πrh

  A = 2(3.1416)(7)(30) = 1319.47 in²

Area of the base and lid

 A = 2 x πr²   = 2(3.1416)(7)²

                      = 307.88 in²

At = 1319.47 in² + 307.88 in²  = 1627.35 in²

pretty sure 750 each month!

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
