Answer:
r = 8
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
16 pi = 2 * pi r
Divide each side by 2 pi
16 pi /2 pi = 2 pi r / 2 pi
8 = r
Answer:
15
Step-by-step explanation:
3 stars = 18
1 star = 6
14-6=8/2 = 4
1 heart = 4
1 spade = -1
4 + -1= 3
3 + (2 stars)
3 + 12 = 15
okey
you needed the sum or division?
Every number has its purpose in this case you start at -3 then the negative sign tells you which way you are going but since we have another negative sign in between the number we go to the right instead of left with that said you put the point in number 4
Perimeter = the addition of all of the side lengths of the polygon.
The side lengths are 9cm, 6cm, 10cm, 5cm, 4cm, and 4cm.
So the perimeter is the following...
Perimeter = 9 + 6 + 10 + 5 + 4 + 4 = 38cm total
