A closed tin of milk has a diameter of 10 cm and height 16 cm , find the total surface area of the tin {take pie to be 22/7}

1. Ms. Sue

Do you know the difference between pi and pie?

2. Anita

sorry my mistake

3. Ms. Sue

:-) It's a common mistake.

Here's the formula.

A=2πrh+2πr2

Can you plug in your numbers?

4. Anita

i am not sure

5. Ms. Sue

6. Ms. Sue

A = (2 * pi * r * h) + (2 * pi * r^2)
