Answer:

The correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.

Step-by-step explanation:

The circumference of table top = 24 $\pi$ inches

We need to find area of table top

The formula used to find area is: $Area = \pi r^2$

We need to find radius of tabletop.

The formula used to find circumference is: $Circumference = 2\pi r$

Putting value of circumference we can find radius

$Circumference = 2\pi r\\24\pi =2\pi r\\r=\frac{24\pi}{2\pi}\\r=12$

So, radius of table top = 12

Now, finding the area:

$Area = \pi r^2\\Area=\pi(12)^2\\Area=3.14(144)\\Area=452.16\:inches^2$

So, the correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.

$750

Step-by-step explanation:

We divide 12 months which is the time Alex would like to be a member by 2 which gives us 6. We know 2 months=$125 so if 2×6=12, $125×6 = A 1 year membership.
