A round jacuzzi has a radius of 135 cm. It is measures 90 cm deep .

To find How many liters of water does the jacuzzi hold, that is to find the volume of the semicirlce.

The formula o find the volume of the semi circle is,

`V=\pi r^2h`

where r= 135 and h= 90.

`\begin{gathered} V=\pi(135)^2\cdot90 \\ =3.14\cdot18225\cdot90 \\ =5150385cm^3 \end{gathered}`

The jacuzzi can hold 5150.385 liters of water.
