Answer:
Step-by-step explanation:
a) circumference = diameter*pi
so, pi in circle A =25.12/8=3.14
pi in circle B = 9.42/3 =3.14
b) area of the circle =(diameter/2)^2*pi
so pi in circle A = 50.24/(8/2)^2=3.14
pi in circle B = 3.14
C) both the value of circle A and B are equivalent
Firstly this looks like translated log function graph
log1=0
As per graph the graph is pulled some inwards y axis but little bit
Usually log x leaves y axis at -1 but here it leaves at +2
So
y axis is moved upwards (+3)
Last function
