Find the volume of a right circular cylinder of a diameter of base 14

1.	Find the volume of a right circular cylinder of a diameter of base 14 cm and height 40cm
Answer» Given : Diameter of BASE of CYLINDER = 14cm. Height of Cylinder = 40cm. To Find : VOLUME of Cylinder. Solution : $\longmapsto\tt{Diameter=14cm}$ $\longmapsto\tt{Radius=\cancel\dfrac{14}{2}=7cm}$ $\longmapsto\tt{Height=40cm}$ Using Formula : $\longmapsto\tt\boxed{Volume\:of\:Cylinder=\pi{{r}^{2}h}}$ Putting Values : $\longmapsto\tt{\dfrac{22}{\not{7}}\times{7}\times{\not{7}}\times{40}}$ $\longmapsto\tt{22\times{7}\times{40}}$ $\longmapsto\tt\bold{6160{cm}^{3}}$ So , The volume of Cylinder is 6160cm³.. _______________________ C.S.A of Cylinder = 2πrh T.S.A of Cylinder = 2πr(r+h) Volume of Cylinder = πr²h _______________________
