It’s 1+1 equal 11 btw I don’t know
The answer is 16 because you have to solve for T which is 4 So you will multiply 4 times 4 because T is for 4 and you had to put parentheses around 4...4×4 is eight and you have to subtract 24-8 and it will give you 16
If the cylinder is closed at both ends the formula is
πdh + 2π(d/2)^2 where h = height and d = diameter
