The radius of the base of a cylinder is 10 centimeters and it hights is 29 centimeters a cone is used to fill the cylinder with water the radius of the cone base is 5 centimeters and it highs 10 centimeters the number of times one need to use the completely filled come to completely filled the cylinder with water

Respuesta :

Answer:

34.8 times

Step-by-step explanation:

Cone

Base Radius of the Cone = 5cm

Height of the Cone = 10cm

Volume of a one [tex]=\dfrac13\pi r^2 h[/tex]

Volume

[tex]=\dfrac13\times \pi \times 5^2\times 10\\=\dfrac{250}{3}\pi $ cm^3[/tex]

Cylinder

Base Radius of the Cylinder = 10cm

Height of the Cylinder = 29cm

Volume of a Cylinder [tex]=\pi r^2 h[/tex]

Volume

[tex]=\pi \times 10^2 \times 29\\=2900\pi$ cm^3[/tex]

[tex]\dfrac{\text{Volume of Cylinder}}{\text{Volume of Cone}}=\dfrac{2900\pi}{\frac{250}{3}\pi }\\=2900 \times \frac{3}{250}\\=34.8[/tex]

A full cone will be used 34.8 times to fill the cylinder with water.
