Answer:
Step-by-step explanation:
If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter
-20-(-5)(-2^2)
-20-(-5)(-4)
-20-(20)
-20-20
-40
Answer:
11
Step-by-step explanation:
Let x be the unknown number
2x+5 = 27
Subtract 5 from each side
2x+5-5 = 27-5
2x = 22
Divide each side by 2
2x/2 = 22/2
x = 11
The number is 11
