# Cylinder - A&V

The cylinder has a volume 1287. The base has a radius 10. What is the area of surface of the cylinder?

Result

A =  885.7

#### Solution:

$r = 10 \ \\ V = \pi r^2 v \ \\ v = \dfrac{ 1287}{\pi r^2} = 4.097 \ \\ A = 2S_1 + S_2 = 2\pi r^2 + 2\pi r \cdot v = 2\pi \cdot 10 \cdot (10+4.097) = 885.7$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
