2 pi 4^2+2pi4x10

To simplify the expression 2π(4^2) + 2π(4)(10), we first need to calculate the value of 4^2 which is equal to 16.

Then, we substitute this value back into the expression:
2π(16) + 2π(4)(10)

Next, we calculate 2π(16) which equals to 32π.
Then we calculate 2π(4)(10) which equals to 80π.

Putting it all together, we get:
32π + 80π = 112π

Therefore, 2π(4^2) + 2π(4)(10) simplifies to 112π.
