The area of a circle (A) with radius "r" is:

To solve this question, follow the steps below.
Step 01: Find r.
The radius is half the measure of the diameter.

Given D = 12 feet, then:

Step 02: Find A.
Use r = 6 feet to find A.

Answer: The area is 36π square feet.

Answer:
V = 125 in^3
Step-by-step explanation:
A cube has 6 sides, and the area of each is equal to the side length squared:
A = 6x^2
A is given as 150 cm^2, and so is equal to 6x^2. Thus, x = the side length = 5 cm.
The volume of the same cube is given by V = x^3, which here is 5^3 in^3, or V = 125 in^3
