Answer:
(a)h(g(133))
(b)f(j(6.82))
Step-by-step explanation:
(a)Area of a circle whose circumference is 133 cm.
Since g(C) represents the radius (in cm) of a circle whose circumference is C cm.
- The radius of the circle whose circumference is 133 cm = g(133)
h(r) represents the area of a circle whose radius is r cm.
Therefore, the area of a circle whose circumference is 133 cm is:
h(g(133))
(b)Circumference of a circle whose area is
j(A) represents the radius (in cm) of a circle whose area is A .
- The radius of the circle of area = j(6.82)
f(r) represents the circumference (in cm) of a circle whose radius is r cm.
Therefore:
- Circumference, f(r) = f(j(6.82))
The circumference of a circle whose area is =f(j(6.82))

It is a 125% increase from 20 to 45
Um 2a is bigger than 2b and -2b would be considered bigger
like -6(-2a) is smaller than -3 (-2b)
