Answer:3:1
Step-by-step explanation:
Given
There are 27 solid spheres of radius x cm
The volume of a sphere is
The volume of 27 old spheres is the same as the volume of a new sphere
The volume of the old spheres is
The volume of a new sphere is
Now,
The circumference of the outer edge of the path around the pool is 113.04 ft.
<h3>What is the circumference?</h3>The Circumference (or) perimeter of circle = 2πR. where, R is the radius of the circle.
Given
A circular swimming pool has a radius of 15 ft.
There is a path all the way around that pool that is three feet wide.
A circle has a radius of 15 feet.
A larger circle goes around the smaller circle that is 3 feet wide.
The radius of the outer edge of the path around the pool = Radius of circle + width of outer circle.
The radius of the outer edge of the path around the pool = 15 + 3
The radius of the outer edge of the path around the pool = 18ft
The circumference of the outer edge of the path around the pool is;
Hence, the circumference of the outer edge of the path around the pool is 113.04 ft.
