Curved surface area = 2*pi*radius*height = 2*3.14*1*3 = 18.84 square feet Area of the 2 ends = 2*pi*radius2 = 2*3.14*12 = 6.28 square feet Total surface area = 18.84+6.28 = 25.12 square feet.
62 square feet
Entire surface area: (2*pi*32)+(6*pi*4) = 42*pi square feet or about 132 sq ft
A cylinder with a diameter of 1 foot and 3 feet high has a surface area of 11 square feet.
13.5 square feet
Surface area without the end caps = 2*pi*2*5 = 62.832 square feet rounded to 3 decimal places
2 x (11 x 3) + 2 x (11 x 3) + 2 x (3 x 3) = 150 square feet
By using the equation 2B+Ph. B=2x3=6ft P=2+2+3+3=10ft h=4ft So, 2(6)+(10)(4)=52 square feet
It is: 2(3*4)+2(3*6)+2(4*6) = 108 square feet
It is 2*(2*3 + 3*4 + 4*2) = 52 square feet.
