Question

Problem Page A manufacturer makes decorative globes out of silver in the shape of a solid sphere. Suppose each sphere has a radius of 1.5 cm. If silver is priced at $6.00 per cm3 , how much will the silver cost to make one solid sphere? Use 3.14 for pi, and do not round your answer.

Answer 1

Answer:

$\ 56.52$

Step-by-step explanation:

step 1

Find the volume of the sphere

The volume of the sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$r=1.5\ cm$

substitute

$V=\frac{4}{3}(3.14)(1.5)^{3}$

$V=9.42\ cm^{3}$

step 2

Find the cost

Multiply the volume by $6.00 per cm^3

$9.42*(6)=\ 56.52$
