he have
when r
Volume=45
we are request to find the volume of the sphere with twice radius (2r)
we can find the volume with the following formula

replacing volume

solving for r

![\sqrt[3]{(135)/(4\pi)}=r](https://img.qammunity.org/2023/formulas/mathematics/college/zjzjcnsb729tnzbjaz5lueu7t1sjjw7zcd.png)
now we find the volume for 2r
![2r=2\sqrt[3]{(135)/(4\pi)}](https://img.qammunity.org/2023/formulas/mathematics/college/738cb8rg9yku7i5cl94p5whrnrxyjw0jw0.png)

![V=(4)/(3)\pi(2\sqrt[3]{(135)/(4\pi)})^3](https://img.qammunity.org/2023/formulas/mathematics/college/1atjdfgl4hefgzl70vmaab4wob9xw14ang.png)



then the volume of a sphere twice a radius is 360 units^3
