Answer:
surface area = 245.04 cm² (nearest tenth)
Step-by-step explanation:
Surface area of a closed cylinder = 
Given:
- diameter = 6 cm ⇒ radius = 3 cm
- height = 10 cm
⇒ surface area = 2 × 
× 3² + 2 × × 3 × 10
= 78
= 245.04 cm² (nearest tenth)
Answer:
C.) 418 cm²
I hope this helped you : )
Step-by-step explanation:
First, you find the area of the square:
