Question

Please help me find the correct answers ​

Answer 1

Answer:

1) 63cm²

2)28.27cm²

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

Step-by-step 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.

$\pi \times 3 ^{2} = 28.27433388$

but its asking you to round to the nearest hundredth so

28.27cm²
