Question

Please help me find the correct answers ​

Answer 1

1) 63cm²

2)28.27cm²

(dont put the cm² in your answer though since its already there)

Explanation:

Surface area of the cardboard part formula :

Base × Height

you have the radius going half way so add another 3cm to make it 6cm so you have the full length

6 x 10.5= 63cm²

Plastic part of the can :

`\pi \: r^(2)`

3cm is your radius so.

`\pi * 3 ^(2) = 28.27433388`

but its asking you to round to the nearest hundredth so

28.27cm²
