Answer:
439.8 cm²
Step-by-step explanation:
The new cylinder can has a radius of 5cm and a height of 9cm how many centimeters of aluminum will it take to make this new cylinder can
We are to find the Total Surface Area of this cylinder
The formula is given as:
A=2πrh+2πr²
A =2× π × 5 ×9 + 2 × π × 52
= 439.82297 cm²
Approximately = 439.8 cm²
It would take 439.8 square centimeters of aluminum to make this cylindrical can
