What would be the volume of (a) air (b) plastic in a ball with 25cm diameter made from plastic 2mm thick?
morpeh [17]

Answer:

Part a) The volume of the air is V=7,794.78\ cm^{3}

Part b) The volume of the plastic is V=386.45\ cm^{3}

Step-by-step explanation:

we know that

The volume of the sphere is equal to

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

step 1

Find the volume of the complete ball (air +plastic)

we have

r=25/2=12.5\ cm ------> the radius is half the diameter

substitute

V=\frac{4}{3}\pi (12.5)^{3}

V=8,181.23\ cm^{3}

step 2

Find the volume of the air

we have that

The plastic is 2 mm thick

Convert to cm

2 mm=2/10=0.2 cm

so

The radius of the interior of the ball is

r=12.5-0.2=12.3\ cm

substitute

V=\frac{4}{3}\pi (12.3)^{3}

V=7,794.78\ cm^{3} -----> this is the volume of the air (interior of the ball)

step 3

Find the volume of the plastic

we know that

The volume of the plastic is equal to the volume of the complete ball minus the volume of the air

so

8,181.23\ cm^{3}-7,794.78\ cm^{3}=386.45\ cm^{3}
