Step-by-step explanation:
The area of a circle is given by :
A = πr²
r is the radius of the circle
(4) Diameter = 22 cm
Since, radius = diameter/2
r = 11 cm
Now, area of the circle,

(5) Diameter = 30 cm
Since, radius = diameter/2
r = 15 cm
Now, area of the circle,

(6) Diameter = 4cm
Since, radius = diameter/2
r = 2 cm
Now, area of the circle,

So, the area of circles 4,5 and 6 are 380.13², 706.85² and 12.56² respectively.
D has the commutative property because it just flip flopped the numbers.

Answer:
Delta does not have a relative extreme in the equation, so it is variable y It can not be true
Step-by-step explanation:

There is an answer
The rest of the equation that has no substituted delta is not true, so the prime variables have relative extremes.
