Hey!
So what you can do is:
1 x 1.5 = 1.5(2nd term)
1.5 x 1.5=2.25(3rd term) x 1.5=3.375(4th term) x 1.5 = 5.0625(5th term)

5.0625 x 1.5=7.59375(6th term)x1.5=<span> 11.390625

</span>11.390625 x1.5= 17.0859375(8th term)x1.5=<span> 25.62890625</span>(9th term)

The answer is D!
Hope this helps!

Answer:

  25π/4 square meters

Step-by-step explanation:

The area of a circle is given by the formula ...

  A = πr² . . . . . where r is the radius of the circle.

The radius is half the diameter, so is (1/2)(5 m) = 5/2 m. Using this in the area formula, we find the area to be ...

  A = π(5/2 m)² = (25/4)π m²

The area of the circle is 25π/4 square meters.

__

As a decimal, that is 6.25π square meters.
