Since the circumference is a little greater than 3 times the diameter, π is a number that is a little greater than 3. Use the symbol π to represent this special number. Pi is a non-terminating, non-repeating decimal, and mathematicians use the symbol π or approximate representations as more convenient ways to represent pi. π = 3.14 or 227
Find the circumference of the circle in the picture.

about 69.54 cm

Step-by-step explanation:

The diameter of a circle is given to be 21 centimetres. The formula for circumference of a circle given the diameter is πd, where d is the diameter and π is constant equal to 3.14... The question tells us to use 3.14, giving us the equation 3.14*21 cm. This multiplication results in 69.54 cm.

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.

show us the graphs dude
