Question

tennis ball has a radius of 6.7 centimeters. What is the volume of a tennis ball? Use 3.14 for pi. Round your answer to the nearest hundredth.
157.48 cm3
1259.19 cm3
4188.79 cm3
9634.08 cm3

Answer 1

What shape is a tennis ball? :)

Answer 2

Round a circle

Answer 3

So a sphere :P

Answer 4

Sphere

Answer 5

Volume of a sphere=
\[\huge~\rm~\bf~V=\frac{ 4 }{ 3 }(\pi)(r^3)\]

Answer 6

we are given the radius so we can plug it in

Answer 7

So would it be 157.48

Answer 8

Volume of a sphere=
\[\huge~\rm~\bf~V=\frac{ 4 }{ 3 }(\pi)(6.7^3)\]

^that will get you the answer
Can you show me how you got that?

Answer 9

I tried to do what you said sorry I am new to this type of math

Answer 10

Volume of a sphere=
\[\huge~\rm~\bf~V=\frac{ 4 }{ 3 }(3.14)(6.7^3)\]

^that will get you the answer
\[\huge~\rm~\bf~6.7^3=6.7*6.7*6.7=? \]

Answer 11

300.763

Answer 12

Volume of a sphere=
\[\huge~\rm~\bf~V=\frac{ 4 }{ 3 }(3.14)(6.7^3)\]

\[\huge~\rm~\bf~6.7^3=6.7*6.7*6.7=300.763\]
\[\huge~\rm~\bf~V=\frac{ 4 }{ 3 }(3.14)(300.763)\]

\[\huge~\rm~3.14*300.763=?\]

Answer 13

944.39582

Answer 14

Good
Volume of a sphere=
\[\huge~\rm~\bf~V=\frac{ 4 }{ 3 }(3.14)(6.7^3)\]

\[\huge~\rm~\bf~6.7^3=6.7*6.7*6.7=300.763\]
\[\huge~\rm~\bf~V=\frac{ 4 }{ 3 }(3.14)(300.763)\]

\[\huge~\rm~3.14*300.763=944.39582\]

\[\huge~\rm~\bf~V=\frac{ 4 }{ 3 }(944.39582)\]
\[\huge~\rm~\bf~V=\frac{ 4 }{ 3 }*(944.39582)=?\]

Answer 15

1259.19

Answer 16

Yep and that would be our answer :)

Answer 17

Thank you you really helped

Answer 18

haha no problem! ^_^
