Answer:

The amount of tinplate is
$2500\pi$

Explanation:

We have to find amount tinplate used in 10 cylindrical cans

So, we will find surface area of one can

and then we can find total surface area

that would be total amount of tin plate

we are given

diameter=d=10cm

so, radius=r=5cm

height=h=20cm

now, we can find surface area

$S=2\pi rh+2\pi r^2$

now, we can plug values

$S=2\pi (5)(20)+2\pi (5)^2$

$S=200\pi +50\pi$

$S=250\pi$

now, we can find total amount of tin plate

$T=10* 250\pi$

$T=2500\pi$
