Question

find the radius of right circular cylindrical whose volume is 3080 cm cube and height is 20 centimetres

Answer 1

Hey friend

Given-:
Volume of cylinder=3080cm³
Height of cylinder=20cm

To Find-:
Radius of Cylinder=?

Solution-:
=>Volume of cylinder=πr²h
=>3080=22/7×r²×20
=>154=22/7×r²
=>49=r²
=>Radius=7

So, the radius of right circular cylinder=7cm.


Be perfectionist

Answer 2

given volume of right circular cylinder V= 3080cm^³

πr^²h= 3080

22/7×r^²×20=3080

r^²=3080×7/20×22


r^²=21560/440=49

r= √49= 7

so answer is 7 cm

radius= 7 cm

hope it help you
