PLZ HELP I HAVE NO CLUE WHAT TO DO

If you're wanting to know the surface area of the cylinder, then"

surface area=1074.41 in^2

Step-by-step explanation:

area of one end=pi(r^2)=3.14(9^2)=254.47

two ends=254.47(2)=508.94

vertical side=pi(2r)(height)=3.14(18)(10)=565.47

565.47+508.94=1074.41

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

squares, rhombus, rectangles
