Answer:
37.3032cm^2
Step-by-step explanation:
Given data
Diameter= 0.6cm
Radius= 0.3cm
Lenght = 19.5cm
Surface area (A) =2πrh+2πr^2
Substitute
A=2*3.14*0.3*19.5+2*3.14*0.3^2
A=36.738+0.5652
A=37.3032
Hence the surface area is
37.3032cm^2
The answer is 13+9u-5y... I THINK! x3
I circle all the positives and negatives, which you can detect by what is in front of the number, like 3y-8y, 8y is a negative. So, you subtract to get -5y.
The rest are positives, so you just add all the letters to what it matches to be, and constants too.
Then... You get your answer? I'm not sure how to get them in their exact order... can someone help me? x3
