Answer:
![B_2=4\pi r^2](https://tex.z-dn.net/?f=B_2%3D4%5Cpi%20r%5E2)
see the explanation
Step-by-step explanation:
we know that
The area of the base of a cylinder is given by the formula
![B=\pi r^{2}](https://tex.z-dn.net/?f=B%3D%5Cpi%20r%5E%7B2%7D)
where
r is the radius of the circular base
If the radius is doubled
then
![r=2r](https://tex.z-dn.net/?f=r%3D2r)
The new base area is
![B_2=\pi (2r)^{2}](https://tex.z-dn.net/?f=B_2%3D%5Cpi%20%282r%29%5E%7B2%7D)
![B_2=4\pi r^2](https://tex.z-dn.net/?f=B_2%3D4%5Cpi%20r%5E2)
so
![B_2=4B](https://tex.z-dn.net/?f=B_2%3D4B)
therefore
The new area of the base is 4 times the area of the original base
