Question

Q. 15 Volume of right circular cone of
radius 6 cm and height 7 cm is
А
1892 cm3
3
B 66 cm
c 264 cm
D
132 cm3​

Answer 1

Answer:

answer I 660

Step-by-step explanation:

v= π r^2 h/3

v= 22/7 × 6 × 7/3

v= 22 × 2

v= 44 cm^3

therefore

15 cones volume is

44 × 15

= 660cm^3

Answer 2

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

GIVEN :-

• Radius and height of a right circular cone is 6cm and 7 cm.

TO FIND :-

• It's volume !

DIAGRAM :-

$\setlength{\unitlength}{1.2mm}\begin{picture}(5,5)\thicklines\put(0,0){\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\put(-0.5,-1){\line(1,2){13}}\put(25.5,-1){\line(-1,2){13}}\multiput(12.5,-1)(2,0){7}{\line(1,0){1}}\multiput(12.5,-1)(0,4){7}{\line(0,1){2}}\put(18,1.6){\sf{6cm}}\put(9.5,10){\sf{7cm}}\end{picture}$

FORMULA :-

$\sf\:\:\:\:\:\:\bullet\:{Volume\: of \:right\: circular\: cone \:= \:\dfrac{1}{3}\pi r^2 h}$

SOLUTION :-

Putting all values in the formula :-

➱ $\sf\:\:\:{\dfrac{1}{3}\:\times\:\dfrac{22}{7}\:\times\:(6)^2\:\times\:7}$

➱ $\sf\:\:\:{\dfrac{1}{3}\:\times\:\dfrac{22}{7}\:\times\:36\:\times\:7}$

➱ $\sf\:\:\:{\dfrac{1}{\cancel{3}}\:\times\:\dfrac{22}{\cancel{7}}\:\times\:\cancel{36}\:\times\:\cancel{7}}$

➱ $\sf\:\:\:{1\:\times\:22\:\times\:12\:\times\:1}$

➱ $\sf\:\:\:{22\:\times\:12}$

➱ $\:\:\:\boxed{\sf{264\:cm^3}}\:\orange\bigstar$

$\underline {\boxed {\sf {\therefore \green {(C)\:264\:cm^3\:is \:correct\:option}}}}\:\red\bigstar$
