Question

I just want answer so no need for explanation. Thank you

Answer 1

we know that

the volume of a sphere is equal to

`V=(4)/(3)\pi\cdot r^3`

we have

r=16.2/2=8.1 cm -----> the radius is half the diameter

pi=3.14

substitute the given values

`\begin{gathered} V=(4)/(3)\cdot(3.14)\cdot8.1^3 \\ V=2,225.0\text{ cm\textasciicircum{}3} \end{gathered}`

the volume is 2,225.0 cubic centimeters
