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}
2πrh+2πr²
2×22/7×5×16+2×22/7×5²
44/7×80+44/7×25
3520/7+1100/7

660cm
I want to learn
2πr(h+r)
2π×20(16+10)

Pls A closed tin of milk has a diameter of 10cm and height 16cm find the total surface area of the tin take pie 22 over seven show full working
I haven’t gotten my answer
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
Me too i did not understand
2×22/7×10(#16)
Ans=660 cm
A closed tin of milk has diameter 10 cm and height 16 cm • find the total surface area of thetin •( take π to be 22/7•
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).
660cm
Yes, that is correct.
Do you know the difference between pi and pie?
2*22/7*16+2*22/7*10
Mahd ooo e hard
sorry my mistake
:-) It's a common mistake.
Here's the formula.
A=2πrh+2πr2
Can you plug in your numbers?
