The sum of the radius of the base and height of a solid right Circular cylinder is 37cm .if it's total surface area is 1628cm² find its volume. |

Answer» Answer: Given r+h=37 cm Total SURFACE area of the SOLID CYLINDER = 2πr(r+h)=1628cm
∴r= 2×22×37 1628×7
=7cm ∴ Height = (37-7) cn = 30 cm and Circumference = 2πr= 7 22
×7=44cm Volume of the cylinder = πr 2 h= 7 22
×7×7×30=4620cm 3 |
