The radius of the circular garden whose circumference is 122.46 feet is: 19.5 feet.
<h3>What is the Circumference of a Circle?</h3>
Circumference = 2πr, where r is the radius of the circle.
Given the following:
- Circumference = 122.46 feet
- Radius (r) = ?
- π = 3.14
122.46 = 2(3.14)(r)
122.46/2(3.14) = r
r = 19.5 feet.

)
x = n ⇒ x = 
Given
(9x) - 3 = 3
(
) = 3
3x = 3
3x = 2³ = 8 ( divide both sides by 3 )
x =
Because algebra means finding the unknown
it is usually used in real life
for example if if 1/2 of the legnth of a line is 8 then what is the legnth
so then 1/2 x=8 and that is algebraic
since it has x, or an unknown in it, it is an algebraic expression
