Answer:
pi x diameter
Step-by-step explanation:
To calculate the circumference of a circle, simply multiply pi (3.14) by the diameter (straight line passing from side to side through the center of the circle)
For instance, if you knew the diameter of a circle was 6 inches. Simply multiply 6 inches by pi!
6 x pi = ?
? approximately equals 18.85 inches.
The circumference of the circle would be 18.85 inches!
If you only have the radius of the circle, simply multiply it by two to get your diameter. Remember, the radius is just half the length of the diameter.
Hope this helps! :)
Answer:

Step-by-step explanation:
I used the clculater
X-18 = 2 (X-25)
x-18 = 2x - 50
-18 = x - 50
32 = x
check
32-18 = 14 = 2(32-25) = 2*7
32 is the answer
Answer:

Step-by-step explanation:
Convert 15300 to a percent,
We can convert it to it's lowest fraction,
120, and to find the percent just multiply it by 5 on top and bottom,
120 ×5×5
which equals, 5100
Then take the percent as a decimal, 0.5 and multiply it by 12500,
12500×0.5 which would give you: 625
