Here is the pic, pls solve it, I am very bad at these stuff.

About 339.12 (using 3.14)

About 339.29 (Using PI function on a calculator)

It should say on top if you should use 3.14 or the pi function

Step-by-step explanation:

So find the areas of the circle first, the radius is 3 so we square that and times pi becuase circle of area is pi*raidus^2

So you’ll get 9 Pi

Now there are 2 so we double that

Thats 18 Pi

Now the middle, I‘d like to think of t like a soda can, if you slice a line in the middle And flatten out the curve, you’ll get a. Rectangle which is L*W. Now we know one side (15) and now the other side is just the circumfrcne of the circle (Circumfrnce is the pereimtr of the circle). Now Circumfrnce formula is either 2*radius*pi or just pi*diameter. So we only have radius so 3*2 is 6, 6*pi is 6 pi. Now we multiply 6 pi and 15 which is 90 Pi. Now 90 pi + 18 Pi is 108 pi. Now it depend on what the directions asked, if asked to use 3.14 for pi, its about 339.12 but if asked to use pi function, it’s be 339.29. If asked to use other less common ones, use multiply the thing they asked you to use by 108.

b. hoped i'm right lol
