.)
(By the order of operations, we take care of the exponents before whatever else we have here.)
(By the order of operations, we take care of the multiplication as we see if left to right.)
(By the order of operations, we perform addition/subtraction as we see it left to right.)

Answer:
The answer is 28.26 square in
Step-by-step explanation:
As, the diameter if the top = 6 inches
And the area of a circle = 3.14(pi) x radius^2
So here radius = Diameter /2 = 6/2 = 3
So radius = 3 inches
So area = 3.14 x (3)^2
= 3.14 x 9
= 28.26 square in
