Volume of c1is 4312 cm².
Step-by-step explanation:
Given:-
Radius of cylinder is 7 cm.
To find:-
Volume of cylinder.
Solution:-
Diameter = Radius × 2
= 7 × 2
= 14
Diameter of cylinder is 2
It is given that, height is double the diameter of cylinder.
So,
Diameter is 14 cm
Height = 14 × 2
= 28
Height of cylinder is 28 cm.
Diagram :-
\setlength{\unitlength}{1mm}\begin{picture}\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\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)}\multiput(18,2)(0,32){1}{\sf{7 cm}}\put(9,17.5){\sf{28 cm}}\end{picture}
Now,
Volume of cylinder is πr²h
Where,
r is radius and h is height of cylinder.
Put r and h in formula
\longrightarrow⟶ 22/7 × (7)² × 28
\longrightarrow⟶ 22/7 × 7 × 7 × 28
\longrightarrow⟶ 22 × 7 × 28
\begin{gathered} \longrightarrow \purple{\boxed{\sf \bold{4312}} \star } \\ \end{gathered}
⟶
4312

Therefore,
Volume of cylinder is 4312 cm².
