If the curved surface area of a cylinder is 126π cm²
and its height is 14 cm. then, what is the volume of the cylinder?Solution
given - height = 14cm the curved surface area of a cylinder = 126 Ï€ 2Ï€rh = 126Ï€ 2Ï€ × r× 14 =126Ï€ r = 9/2= 4.5 cm so now the volume of the cylinder = Ï€r²h =4.5×4.5×14 × Ï€ =(9×9×7) Ï€/2 =567Ï€/2 =283.5Ï€ cm³Â
