Answer:

A = 200.96 cm²

Step-by-step explanation:

Formula for surface area of cylinder

A = 2πrh + 2πr²

Formula for radius

r = 1/2(diameter)

r = 1/2(8cm)

r = 4 cm

A = 2π(4cm)(4cm) + 2π(4cm)²

A = 2(3.14)(4 cm)(4cm) + 2(3.14)(4cm)²

A = 100.48 cm² + 100.48 cm²

A = 200.96 cm²

Answer:

surface area of a cylinder is 2πr (r+h), 400sq.cm
