no proof but a g00gle calculator, you're just gonna have to trust me on this one

SA = 376.8 in²

Step-by-step explanation:

area of top:

π4² = 50.24 in²

50.24 x 2 = 100.48 in²   (for both ends)

area of side:

circumference = 2 x 4 x π = 25.12 in

area = 25.12 x 11 = 276.32 in²

276.32 + 100.48 = 376.8 in²

i used to know but i learned it a long time ago sorry

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
