Question

find the volume of right circular cone with r=16 cm , h=17 cm​

Answer 1

Given :

• Radius and Height of a Cone is 16 cm and 17 cm respectively .

To Find :

• Volume of Cone .

Solution :

$\longmapsto\tt{Radius=16\:cm}$

$\longmapsto\tt{Height=17\:cm}$

Using Formula :

$\longmapsto\tt\boxed{Volume\:of\:Cone=\dfrac{1}{3}\pi{{r}^{2}h}}$

Putting Values :

$\longmapsto\tt{\dfrac{1}{3}\times\dfrac{22}{7}\times{16}\times{16}\times{17}}$

$\longmapsto\tt{\dfrac{22\times{16}\times{16}\times{17}}{21}}$

$\longmapsto\tt{\cancel\dfrac{95744}{21}}$

$\longmapsto\tt\bf{4559.2\:{cm}^{3}}$

So , The Volume of Cone is 4559.2 cm³ ..

_______________________

• C.S.A of Cone = πrl
• T.S.A of Cone = πr(l+r)
• Volume of Cone = ⅓ πr²h

Here :

• r = radius of cone
• l = slant height of cone
• h = height of cone

Answer:

$\huge \bf \: given$

• R - 16 cm
• H - 17 cm

$\huge \tt \: answer$

Here,

'R' Stands for radius and 'H' stands for height.

$\huge \tt \: formula \: = \: \frac{1}{3} \pi \: {r}^{2} h$

$\frac{1}{3} \times \frac{22}{7} \times 16 \times 16 \times 17$

$\frac{22 \times 16 \times 16 \times 17}{21}$

$\frac{95744}{21}$

$\bf \: {4559.2}^{3}$

So, the volume of cone - 4559.2³ cm
