The required radius of the cylinder that can be covered by the paint exists at 3.8 feet.
Franco has enough paint to protect an area of about 226 square feet. He must paint a cylinder that exists 5 feet, and the maximum possible radius of the cylinder that can be covered by the paint exists to be determined.
<h3>What is a cylinder?</h3>The cylinder exists described as a 3D solid that holds two identical bases joined by a curved surface, at a particular distance.
Here, Franco keeps sufficiently paint to cover an area of about 226 square feet.
Area of the cylinder = 226
Area of the cylinder = πr²h = 226
h = 5 feet and π = 3.14
3.14 5
r² = 226
r² = 226/15.70
r = 3.80
Therefore, the required radius of the cylinder that can be covered by the paint exists at 3.8 feet.
