Answer 1

Answer:

1/6 or 1:6

Step-by-step explanation:

The given question is as follows :-

Point A and B lie on a circle with radius 1 , and arc AB has a length of π/3 . What

fraction of the circumference of the circle is the length of arc AB ?

Solution :-

Length of arc AB/ circumference = (π/3)/2.π.r. = (π/3)/2.π.1 = 1/6 or 1 : 6. Answer.

Answer 2

Answer:

N = 45

average no. of shoppers = 90

Shoppers per hour = 60

no.of shoppers/ time = 90/60 = 1.5 shoppers per min

r = 1.5

T (time) = 12 mins

So using formula

N = rt = 1.5 × 12 = 18

So to calculate %

=

\frac{45 - 18}{45} \times 100

45

45−18

×100

= 60

hence 60 % less than average no. of shoppers in the orginal store .
