Which statement is true about all cylinders

Option 3rd is the right answer.

Step-by-step explanation:

Lets check the given statements.

1)The height is a vertical distance - The height of the cylinder is the perpendicular distance between both the bases of the cylinder.

2)The diameter of a base is less than the height - Both the diameter and height can be equal. Its not always true that the diameter is less than height.

3)The radii of both bases are the same - Both the bases will have the same radius in any cylinder.

4)The area of a base is greater than 1 square unit - This is not justifiable.

So, only option 3 is the true statement here.

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.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
