Answer:
Total amount = R5112
Step-by-step explanation:
Let the cooks be C.
Let the waiters be W.
Given the following data;
Number of cooks, C = 2
Number of waiters, W = 3
a. To find the amount earned by each cook;
C = 36 * R36 = R1296
b. To find the amount earned by each waiter;
W = 30 * R28 = R840
c. To find the total amount earned by the employees;
Total amount = 2C + 3W
Total amount = 2(1296) + 3(840)
Total amount = 2592 + 2520
Total amount = R5112
Im not 100% sure but I do think it is Ratio (red to blue) of the areas
Step-by-step explanation:
Given:
Circle C and circle R are similar.
The length of arc AB is 
The radius of circle C (AC) = 4 unit
The radius of circle R (QR) =6 unit
To find the length of arc QP.
Formula
The relation between s, r and
is

where,
s be the length of the arc
r be the radius
be the angle.
Now,
For circle C
Taking r = 4
According to the problem,

or,
[ eliminating
from both side]
or, 
or, 
Again,
For circle R
Taking, r = 6 and
we get,
The length of arc QP is

or, 
Hence,
The length of QP is
. Option C.
