Question

The volume of a cylinder is 308 cm cube with radius 7 cm find the height

Answer 1

Answer:

h = 2 cm

Step-by-step explanation:

Given,

The volume of the cylinder(v) = 308cm³

the radius(r) = 7cm

height  (h) = ?

       from formula,

       v = πr²h

or, 308 = 3.14 × 7² × h

or, 308 = 153.86 × h

or, 308/153.86 = h

∴ h = 2cm  

Answer 2

Answer:

Volume of cylinder=308cm

radius of cylinder=7cm

V=πr2h

308=22/7×7×7×h

308=22/7×49×h

308=22×7×h

308=154×h

308/154=h

2=h

therefore,height is 2cm.
