Question

The height of a cylinder is 80 cm and diameter of base is 7 m, the volume of right circular

cylinder is:​

Answer 1

Answer:

15.4m³

Step-by-step explanation:

given, height of cylinder, h = 80cm = 0.8m       ( As 1m = 100cm)

also, given diameter of the cylinder = 2r = 7m

=> radius, r = 7/2 m

so, the volume of the cylinder = $\pi$r²h cu.units

                                                  =  $\frac{22}{7}$*$\frac{7}{2}$*$\frac{7}{2}$*0.8 m³

                                                  = $\frac{11}{1}$*$\frac{7}{1}$*0.2m³

                                                  = 15.4m³
