Acylindrical grain bin has a radius of 9 feet and a height of 30 feet. what is the surface area of the bin? 1,808.63 ft^2 1949.94 ft^2 1,356.48^2 2,204.28 ft^2

Surface area of bin is:

2204.28 ft²

Step-by-step explanation:

Surface area of bin=Surface area of cylinder

We know that surface area of cylinder is given by:

A = 2πrh + 2πr²

where r is the radius of the cylinder and h is the height of the cylinder

Here, r=9 ft and h=30 ft

Assuming π=3.14

A = 2×3.14×9×30 + 2×3.14×9×9

A = 2204.28 ft²

Hence, surface area of bin is:

2204.28 ft²

uhhh idk u yolo?
