Question

Zuri made 2 spheres using plaster. The smaller sphere has a radius of 6 cm. The larger sphere has a radius of 24 cm.

How much more plaster did Zuri use for the larger sphere?
Use 3.14 to approximate pi and express your answer in hundredths.


cm3

Answer 2

Find volume of each

volume of a sphere is 4/3 times pi times radius^3

so first calculate the smaler sphere
radius=6
pi is aprox 3.14
4/3 times 3.14 times r^3
4/3 times 3.14 times 6^3
4/3 times 3.14 times 216
904.32 cm^3=volume

volume of larger
radius=24
4/3 times 3.14 times 24^3
4/3 times 3.14 times 13824
57876.48 cm^3

so then subtract the volume of the smaller sphere from the larger sphere

57876.48-904.32=56972.16 cm

he used
56972.16 cm^3 plaster

I think you mean to the hundreth's place which is the place denoted by the x in 0.0x so it is to the hundreth's place

he used
56972.16 cm^3 plaster
