The rise of the segmental arc is 10 cm, its span
is 100 cm and IZXI = IZYI = 120 cm.
Calculate, taking a to be 22 where necessary,
a) the radius of the circle
b) the area of the segmental cap, correct to
2 significant figures
c) the total area of the design, correct to
3 significant figures. (WAEC/SSCE]

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°

the answer is  

d.

121π mi^2

hope you got it chief
