Question

The volume of hemisphere of radius 9cm?​

Answer 1

Answer:

1,527.429 cm³

Step-by-step explanation:

Volume of hemisphere= (2/3)πr³  

                                      = 2/3×22/7×9×9×9  

                                      = 1,527.429 cm³

Answer 2

Given: The radius of the hemisphere is$9$ cm.

We have to find the volume of the hemisphere.

• As we know that the formula is used to calculate the volume of the hemisphere is:
• The volume of a hemisphere = $(2/3)\pi r^3$ cubic units.
• Where π is a constant whose value is equal to 3.14 approximately.
• “r” is the radius of the hemisphere.

We are solving in the following way:

We have,

The radius of the hemisphere is$9$ cm.

So, the volume of the hemisphere will be:

$(2/3)\pi r^3$

$=>\frac{2}{3} \times 3.14\times9^3\\\\=>\frac{2}{3} \times 3.14\times729\\\\=>\frac{157}{75} \times729\\\\=>\frac{38151}{25}$

Hence, the volume of the hemisphere will be$\frac{38151}{25}$$cm^3$.
