The answer is: The surface area of the sphere.
The explanations for this exercise is shown below:
By definition, the surface area of a sphere is four times the area of a circle.
You have that the area of a circle is:

Where
is the radius of the circle.
Therefore, to calculate the surface area of a sphere with radius
, you only need to multiply the equation shown above by four, as following:

Answer:
$3.4
Step-by-step explanation:
Total amount spent by Mila equals $71.05
She bought 5 yards of fabric at $12.85 per yard. Hence, the total amount she spent on fabric is 12.85 × 5 = $64.25
It should be noted that since she bought only 2 kinds of things, this mean that Amount spent of fabric + Amount spent on thread = $71.05
Amount spent on thread = $71.05 - Amount spent on fabrics.
Amount spent on thread = $71.05 - $64.25 = $6.8
This is the total amount spent on thread.
But the question asks amount spent on one spool of thread. Since 2 spools would cost $6.8, one spool would cost $6.8 ÷ 2 = $3.4
