Given the context, generate a math expression.
Calculate the area of a cylinder with a height of 10cm and a radius of 8cm.
The formula for calculating the area of a cylinder is `2 * π * radius * (radius + height)`. So, substituting the height and radius, the expression for calculating the area of a cylinder with a height of 10cm and a radius of 8cm is `2 * π * 8 * (8 + 10)`.
Complete the following task based on the instruction and optional input provided.### Instruction:
