Answer:
59.1 feet
Step-by-step explanation:
The formula for the circumference of a circle in C=2πr. Since the radius of the circle is given, all you have to do is plug it into the equation.
C=2πr
C=2π(9.4)
C=18.8π feet <-- this is the exact answer
<u>C=59.1 feet</u>
Jayla= x
keisha= x+ 3
melanie= x + 6
to solve:
42= x + x + 3 + x + 6
42= 3x + 9
-9 -9
33=3x
———-
3
x=11
therefore
jayla is 11
keisha is 14
melanie is 17
They are the same answer. .7 is in the 10th place which is the same as .70 just adding a zero doesn’t change the number
r = s i n 2 θ , r = c o s 2 θ.
