Step-by-step explanation:

Using the ratio equality for circles

=

(a)

Note the angle at the centre of the shaded arc is 360° - 90° = 270°, thus

= = ( cross- multiply )

3C = 180 ( divide both sides by 3 )

C = 60 mm

(b)

Note the angle at the centre of the shaded arc is 360° - 135° = 225°, thus

= ( cross- multiply )

225C = 1188 ( divide both sides by 225 )

C = 5.28 cm

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

c. (3,2,6) is the answer.
