Answer:
2:1
Step-by-step explanation:
Circle P has radius 14 feet.
The circumference of this circle is given by:
We plug in the radius to get:
Circle Q has diameter 14 feet.
The circumference of this circle is given by
We substitute the diameter d=14 to get,
The ratio of the circumference of P to the circumference of Q is
The containers must be spheres of radius = 6.2cm
<h3>How to minimize the surface area for the containers?</h3>
We know that the shape that minimizes the area for a fixed volume is the sphere.
Here, we want to get spheres of a volume of 1 liter. Where:
1 L = 1000 cm³
And remember that the volume of a sphere of radius R is:
Then we must solve:
The containers must be spheres of radius = 6.2cm
