Circumference and area

Question

Anna is covering the circular pool with a heavy-duty cover for the winter. The pool has a diameter of 24 feet. The cover extends 12 inches Beyond the Edge of the pool and a rope runs along the edge of the cover to secure the cover in place. What is the area of the cover? What is the length of the Rope?

Answer 1

The diameter of the pool is 24 feet.

The diameter of the cover is 26 feet - 24 + 12in + 12in.

The circumference of the cover is 26π (C = πd)

 

The radius of the cover is 13 feet

The area of the cover is 169π (A = πr²)
