let x = radius of flowerbed
The entire area =
If you know the entire area you will know x and the diameter will be 2x
Help I can't figure out an equation to solve this word problem..
A cement walk 1 meter wide is constructed around a circular flower bed. The Area of the flower bed is 9/16 of the entire area (flower bed and walk). What is the diameter of the flower bed?
you know that is 9/16 of
, splitting the middle term;
But we said the diameter of the flower bed is , therefore and as is a length, which must be positive.
