i really need help

[saraha]

a circular fountain 10ft in diameter has a circular walk 3ft wide paved around it. what is the area of the walk?

Draw the picture. What is the radius of the outer perimeter of the walk? What is the total area enclosed within this perimeter?

What is the area of just the fountain?

Subtract the second area from the first. This will give you just the area of the walk.
