Im gonna guess 6.00 beacause it says round to hundreths
Answer:
104.73cm²
Step-by-step explanation:
AREA OF SEMI CIRCLE
9cm-4cm = 5cm
5cm is the radius of the semi-circle
(πr²)/2 =
25π/2 = 12.5π
AREA OF SQUARE
16cm*9cm = 144cm²
AREA OF THE FIGURE SHOWN
144cm² - 12.5cmπ²
144cm² - 39.27cm² = 104.73cm²
A_n= a₁ rⁿ⁻¹
a₁ is the first term
r= common ratio
a_n=2(2)²⁰⁻¹= 1048576
We have a law in geometry called ((power of a node)) the formula is:

according to the formula:
9(FD)=12^2 ==> FD=144/9=16
