Question

find the radius of a cylinder whose volume is 616 cu cm and height is 16 cm

Answer 1

${\mathfrak{\pink{Hola!!}}}$

Given:-
•Volume of cylinder(V)=616cm³
•Height(h)=16cm

To find:-
•Radius(r)

Formula to be used:-
${\green{Volume=πr^2h}}$


616=22/7×r²×16

616×7/22=16r²

4312/22=16r²

196=16r²

r²=196/16

r²=12.25

r=√12.25

r=3.5cm

${\blue{Radius=3.5\:cm}}$

Answer 2

answer

3.5 cm

step by step explanation :

volume of cylinder

616=22/7xr2X16

616x7/22=16r2

4312/22=16r2

196=16 R2

R2=196/16

R2=12.25

r=✓12.25

r=3.5 cm

ans= radius of a cylinder is 3.5 cm
