Question

16. A can in the shape of a cylinder has a diameter of 6 centimeters

Answer 1

Answer:

surface area = 245.04 cm² (nearest tenth)

Step-by-step explanation:

Surface area of a closed cylinder = $2\pi r^2+2\pi rh$

Given:

• diameter = 6 cm ⇒ radius = 3 cm
• height = 10 cm

⇒ surface area = 2 × $\pi$ × 3² + 2 × $\pi$ × 3 × 10

                          = 78$\pi$

                          = 245.04 cm² (nearest tenth)
