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

Answer:

615.752 square cm

Explanation:

Surface area of cylinder:

height = h = 7 cm

radius = r = 7 cm

Plug in the values of r and h in the formula.


\sf \boxed{\text{\bf Surface area of cylinder = $2\pi r(r+h)$}}


\sf = 2*3.14*7 *(7+7)\\\\= 2*3.14*7*14\\\\= 615.752 \ cm^2
