Step-by-step explanation:
The equation of a circle is
where
is the center of the circle and
is the radius of the circle.
Given that
and it passes
, their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:

Therefore, if the length of the radius is
units, then
, making the final equation of the circle 
Yes, 3 yards is bigger than 21 feet because there are 3 feet in a yard.
Step-by-step explanation:
1x+2x+3x=60
x=10
2x+3x+4x=20+30+40=90
average=90÷3=30
Let's represent the number of hours with the variable 'h' (or whatever letter you want it to be):

48h = 288
Divide:
h = 6
