Answer: 4.25
Step-by-step explanation:
2(d-3) + 22d= 120-24
2d - 6 + 22d= 96
2d +22d= 96+6
24d= 102
d= 102/24
d= 4.25

Answer: option C
Step-by-step explanation:
You need to use the formula for calculate the area of a circle:

Where the radius of the circle is "r".
You can see in the figure that the diameter of the circle is 6 meters. Then you need to find the radius of the circle with the formula:

Where "d" is the diameter of the circle.
Then, the radius is:

Finally, substitute the radius into the formula. Then, the area of the circle is:
