Answer:
9th Triangle
Step-by-step explanation:
Given the area of four triangles:
If the Scale factor is 1.5.
This is a geometric sequence and the common ratio is 1.5 X 1.5.
Therefore, the area of any n triangle can be determined using the function:

We want to determine which triangle has an area greater than
.
When A(n)=15000

Therefore, the 9th triangle has an area greater than
.
For the full circle, Area = pi(r)^2
pi x 1^2 = pi
Semi circle = pi/2 = 1.57 square feet

ANSWER
The product is

EXPLANATION
To find the product of

and

means we should multiply the two fractions.
We multiply to obtain,


Cancel the common factors:

Now, multiply the numerators separately and the denominators too separately.

This simplifies to,
