Radius of cone is 6 cm

Step-by-step explanation:

$\sf\small\underline\purple{Given:-}$

$\sf{\leadsto Volume\:_{(cone)}=120π \:cm^3}$

$\sf{\leadsto \: Height\:_{(cone)}=10 cm}$

$\sf\small\underline\purple{To\: Find:-}$

$\sf{\leadsto Radius\:_{(cone)}=?}$

$\sf\small\underline\purple{Solution:-}$

To calculate the radius of cone . Simply by applying formula of volume of cone. As given in the question that height is 10 cm and it's volume is 120 π cm³.

$\sf\small\underline\purple{Calculation\: begin:-}$

$\sf{\leadsto Volume\:_{(cone)}=\dfrac{1}{3}\pi\:r^2\:h}$

$\small \sf \leadsto volume \: of \: cone \: = \frac{1}{3} \pi \times r {}^{2} h \\$

$\small \sf \leadsto \: 120 π cm³ \: = \frac{1}{3} \times\pi r {}^{2} \times 10cm \\$

$\small \sf \leadsto \: 120 π cm³ \: = \frac{10 \: \pi\: cm}{3} \: r {}^{2}$

$\small \sf \leadsto \frac{ 120\pi \: cm {}^{3} \times 3}{10\pi \: cm} \: = r {}^{2} \\ \\$

$\small \sf \leadsto \frac{360\pi cm {}^{3} }{10\pi \: cm} = \: r {}^{2} \\$

$\small \sf \leadsto 36 \:cm {}^{2} = r {}^{2}$

$\small \sf \leadsto \sqrt{36 \: cm {}^{2} } = \sqrt{r {}^{2} }$

$\small \sf \leadsto6cm = r$
