The formula for the total surface area of a cylinder is:
SA = 2πr(r + h)
Where:
SA represents the surface area
π (pi) is a mathematical constant (approximately equal to 3.14)
r represents the radius of the cylinder
h represents the height of the cylinder
To simplify this formula for a 7th grader, you can break it down into steps:
1. Calculate the area of the two circular bases: A = 2πr^2
2. Calculate the area of the curved surface: CS = 2πrh
3. Add the areas of the two bases and the curved surface: SA = A + CS
By breaking down the formula into smaller steps, it becomes easier for a 7th grader to understand and compute the total surface area of a cylinder.
