Answer:
Radius of larger flower bed = 10 feet
Radius of smaller flower bed = 6 feet
Step-by-step explanation:
<u>Complete question:</u>
"You have two circular flower beds, as shown. The sum of the areas of two flower beds is 136 pi square feet. Find the radius of each bed.<em>"</em>
<em>Radius of larger flower bed = r</em>
<em>Radius of smaller flower bed = r - 4</em>
<em />
Now,
Area of circle is
Since, total area is , we can write:
Expanding and solving for r:
Radius cannot be negative, so r = 10 & r-4 = 10 -4 = 6
Radius of larger flower bed = 10 feet
Radius of smaller flower bed = 6 feet
