Answer:
Part 1) The value that is closest to the cost of finishing a sphere with a 5.50-meter circumference is $900
Part 2) The value that is closest to the cost of finishing a sphere with a 7.85-meter circumference is $1,800
Step-by-step explanation:
Step 1
Find the radius of each sphere
we know that
The circumference of a circle is equal to
<u><em>Find the radius of the sphere with a 5.50-meter circumference</em></u>
For
assume
substitute and solve for r
<u><em>Find the radius of the sphere with a 7.85-meter circumference</em></u>
For
assume
substitute and solve for r
step 2
Find the surface area of each sphere
The surface area of sphere is equal to
<u><em>Find the surface area of sphere with a 5.50-meter circumference</em></u>
For
assume
substitute
<u><em>Find the surface area of sphere with a 7.85-meter circumference</em></u>
For
assume
substitute
step 3
Find the cost of finishing each sphere
we know that
To find out the cost , multiply the surface area by $92 per square meter
<u><em>Find the cost of sphere with a 5.50-meter circumference</em></u>
therefore
The value that is closest to the cost of finishing a sphere with a 5.50-meter circumference is $900
<u><em>Find the cost of sphere with a 7.85-meter circumference</em></u>
therefore
The value that is closest to the cost of finishing a sphere with a 7.85-meter circumference is $1,800
