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}
Answered by Ms. Sue
Do you know the difference between pi and pie?
Answered by Anita
sorry my mistake
Answered by Ms. Sue
:-) It's a common mistake.

Here's the formula.

A=2πrh+2πr2

Can you plug in your numbers?

Give it a try, please.

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

Chinenye you made a mistake in your answer 2 and 3
2π×10(16+10)
2×22/7×10(26)

.. but you did well though

First, we need to find the radius of the tin.

The diameter of the tin is given as 10 cm.

∴ radius (r) = diameter/2 = 10/2 = 5 cm.

Using the formula for the total surface area of a cylinder, we get:

Total surface area = 2πrh + 2πr²

Where h = height of the tin = 16 cm

Substituting the values, we get:

Total surface area = 2 × (22/7) × 5 × 16 + 2 × (22/7) × 5²

= (44/7) × 80 + (44/7) × 25

= (3520/7) + (1100/7)

= 4620/7

Hence, the total surface area of the tin is 660 cm² (approx).

Yes, that is correct.
