Question

Can someone double check this? Thanks!

A hard candy has a radius of 9 mm. The candy has a spherical soft center with a radius of 6 mm, with a hard shell surrounding it.


What is the volume of the hard shell?

Use 3.14 to approximate pi and express your final answer in hundredths.

I have 1981.39 is this correct?

Answer 1

you used the formula for the volume of a sphere right?

V = (4/3) pi r^3

Answer 2

Yes.

Answer 3

V = (4/3)π(r)^3

V = (4/3)3.14(9-6)^3

V = (4/3)3.14(3)^3

V = 4/3(9.42)^3

V = 12.56^3

V = 1981.385216

Answer 4

Ok so V hard shell = (4/3) *3.14( 9^3 - 6^3)

Answer 5

Which would equal 2147.76

Answer 6

right

Answer 7

(9 - 6)^3 was not correct

Answer 8

ok

Answer 9

yw

Answer 10

Tysm.
