122 degrees because supplementary angles are 180 degrees
The distance between the two numbers is 23
The equation to get the circumference of a circle is: (C = circumference & r = radius)
C = pi times diameter
The information given:
Radius = 84 inches
What you can get from the information given:
Diameter = 168 inches
So:
C = pi times diameter (168 inches)
C = pi times 168 inches (which is 527.52 inches)
C = 527.52
Hope that helps!
Since there are 28 tens which is basically 28 rows of 10 all you have to do is 28 times 10. Whatever number times ten has a 0 after it so the answer is 280
