Calculate the surface area of a cylinder at waste bucket without a lid that measures 28 cm height and 18 cm in diameter give your answer to the nearest square centimetre

In this situation, the equation that you would be using is A = 2rh+2r²

You have the Diameter: 18, and the height: 28

Since you have to use the radius in the equation, you would divide the diameter by 2 to get the radius, since the radius is half of the diameter.

The radius would be 9.

You will plug in 9 in R, and plug in 28 in H. Your equation would look like this:

2(9)(28)+2(9)²

When you solve the equation, you would get 2092.3 cm. Then you would round it to the nearest whole.

The surface area of the cylinder is 2092 cm²

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
