Question

A circular swimming pool has a radius of 15 ft. There is a path all around that pool that is three feet wide.

Answer 1

Answer:

Circumference(C) of the circle is given by:

$C = 2 \pi r$

where, r is the radius of the circle.

As per the statement:

A circular swimming pool has a radius of 15 ft.

⇒radius of the pool(r) = 15 ft

There is a path all around that pool that is three feet wide.

⇒radius of the outer edge of the path around the pool(r') = 15 +3 = 18 ft

Substitute these in the formula we have;

$C = 2 \pi r'$

⇒$C = 2 \cdot 3.14 \cdot 18 = 113.04 ft$

Therefore, the circumference of the outer edge of the path around the pool is, 113.04 ft
