The formula for the surface area of a cylinder is 2πr² + 2πrh, where r is the radius of the base, h is the height of the cylinder, and π is approximately 3.14159.
Substituting the given values, we get:
Surface Area = 2π(7)² + 2π(7)(7)
Surface Area = 2π(49) + 2π(49)
Surface Area = 98π + 98π
Surface Area = 196π
Rounding to the nearest thousandth, we get:
Surface Area ≈ 615.752 cm²
Hope this helps
