surface area of a cylinder with a radius of 7 and a height of 14 explain step by step in simple terms
measurment is square inches
1. Write down the formula for the surface area of a cylinder: 2πr(r + h), where r is the radius and h is the height of the cylinder.
2. Plug in the values for the radius and height: r = 7 and h = 14.
3. Calculate the surface area using the formula: 2π(7)(7 + 14).
4. Simplify the equation: 2π(7)(21) = 294π.
5. Multiply by π (pi) which is approximately 3.14: 294 * 3.14 = 923.16.
6. The surface area of the cylinder is 923.16 square inches.
