The meaning of circumference is to find the distance around a circle or in other words perimeter by using the formula C=2πr or C=<span>πd.
On this case it is asked you to find the circumference of a circle with a diameter of 3 meters, so you will use the formula C=2</span><span>πr.
C=2</span><span>πr
C=2(3.14)(3)
C=18.84 meters
The circumference of the given circle is 18.84 meters.</span>

ANSWER
For Jamal statement to be true,
EXPLANATION
The given statement is:
ax + b = a(x + c)
We expand the left hand side to obtain,
ax + b = ax + ac
Subtract ax from from both sides of the equation.
b=ac
We know that, a≠0 , so we can divide through by 'a'.
Let the number of hours she works be x
2x+15 15 more than twice the
3x-15 15 less than 3 times the hours she worked
2x+15=3x-15
3x-2x= 30
x= 30
the number of hours she worked is 30
