22

7

​

Answer 1

the anseer is 12.6. the formula of volume of cone is pir2 h/3

Answer 2

Answer:

Step-by-step explanation:

Given:-

• R = 1.4cm
• H = 6cm

• π = 22/7

To Find:-

• Volume of the cone.

Solution:-

$\sf{\longmapsto\:Volume\:of\:the\:cone\:=\:\pi \:r^{2}\:\dfrac{h}{3}}$

$\sf{\longmapsto\:Volume\:of\:the\:cone\:=\:\dfrac{22}{7}\:\times\:(1.4)^{2}\:\times\:\dfrac{6}{3}}$

$\sf{\longmapsto\:Volume\:of\:the\:cone\:=\:\dfrac{22}{7}\:\times\:1.96\:\times\:2}$

$\sf{\longmapsto\:Volume\:of\:the\:cone\:=\:22\:\times\:0.28\:\times\:2}$

$\sf{\longmapsto\:Volume\:of\:the\:cone\:=\:44\:\times\:0.28\:}$

$\sf{\longmapsto\:Volume\:of\:the\:cone\:=\:12.32cm^{3}}$
