Since F(X) = 3^X,
F(4) = 3^4 = 81
Circumference=2πr
2π=2πr
r=1
area=πr^2
area=π(1)^2
area=π
25 + 100i is correct because -5 squared is 25 and the the square root of -100 is 100i or 10i in its simplest form.
It’s 28, 16 add 4 is 20 add 8 is 28

The given two polygons are similar to one another ~
Sides of the given polygons are in ratio of :

to put in simple Ratio ~

So, the sides of the larger polygon are :
Now, to find the Perimeter of larger polygon ~ add the side length of all sides :
