Answer:

x = 9 cm

Explanation:

The formula for the surface area of a cylinder can be written as ...

SA = 2πr(r +h) . . . . . where r is half the diameter, and h is the height

For the given cylinder, we have ...

972π cm² = 2π(x)(x+5x) = 12πx²

Dividing by 12π gives ...

81 cm² = x²

Taking the square root, we have ...

9 cm = x
