in order to find the volume you need the height.
Surface area = π r² + base x height or width x length
1850 = 3.14 × 9² + radius × 2 x π x height
1850 = 254.34 + 9 × 2 × 3.14 × height
1850 = 310.86 × height
To find the height you have to divide the surface area by the part I bolded
Height = 1850 ÷ 310.56
Height ≈ 6
Volume of a cylinder = πr²×height
= 3.14 × 9 × 9 × 6
Volume =1526.04
Nearest whole number would be 1526
