Question

Totalcost pf painting of a 10 m. Height cylindrical. Vessel @of ₹20m^2 is ₹2200.Find internal surface area and volume of a vessel

Answer 1

Answer:

Given: height of cylindrical vessel = 10m

rate of painting = ₹20/m²

cost of painting = ₹2200

ar of cylinder = 2200/20

                      =110m²

2$\pi$rh=110

r=7/4=1.75

volume of cylinder=$\pi r^{2} h$

                              =22/7×(7/4)²×10

                              = 385/4m³

                              =96.25 m³
