Triangle 1 area : 6×4 /2 -> 24/2 -> 12
triangle 2 area : 9×8 /2 -> 72/2 -> 36
rectangle 1 area : 6×4 -> 24

lets take point K represent lenght from M to perimeter of circle.
r is radius
KM= r-OM= r-4.5cm
now lets draw line from O to A (OA)
we get triangle.
hypotenuse is OA and it equals r(radius)
ab=12 cm. so another side of the triangle (AM) is 12/2=6cm. and the last side of the triangle is 4.5(OM)
use pythaghorean theorem
squares of sides added = square of hypotenuse
20.25+36=r^2(our hypotenuse is radius)
56.25=r^2
r=√56.25=7.5cm
The fibonacci spiral appears to be in everyday items such as plants to snail shells. It's basically a numbering system.an example of the Fibonacci sequences is it applies the growth of every living things. For example, rose petals have a Fibonacci number of petals.
If you mean something like 4^3 * 4^14 you have to obey two rules.
1. The base number must be the same for both numbers making up the product.
2. The powers must be added.
In this case 1 and 2 both can be obeyed.
4^3 * 4^14 = 4^(3 + 14) = 4^17
