11. Find the radius of the circle: =
a) when A= 90°, A = 20 cm
b) when = 30°, A = 35 cm2
c) when 0= 150°, A = 114 cm
=

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

the answer is a.

135 and 80

step-by-step explanation:

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
