A rectangular sheet of metal has a length of 42 cm and a breadth of 100 cm. It is folded to form a cylinder with the breadth becoming the height. Calculate a) the radius of the cylinder formed b) the volume of the cylinder [Take 1 = 22) ]
Si el ancho de 100 cm de la hoja se convierte en la altura del cilindro, la longitud de 42 cm debe ser su circunferencia.[matemáticas]\ C = 2 \pi r \implica r = \frac{C}{2 \pi} \approx \boxed{6.68 \ \mathrm{cm}}.[/matemáticas]
