Question

The volume of a cylinder in cm cube is equal to curved surface of a cyclinder in cm square .Find the diameter of cylinder​

Answer 1

The radius 'r' of a cylinder is the radius of its base. Now, the area of the rectangle = length × breadth. 2πr is the circumference of the circle and h is the height. Area of the curved surface will be = 2πr × h = 2πrh.

Answer 2

Answer:

Step-by-step explanation:

4cm

Step-by-step explanation:

we know that the volume of cylinder is, (πr²h) cm³

and curved surface area is, (2πrh) cm²

now, acc. to the question condition, volume of cylinder = curved surface

area of cylinder

so, (πr²h)cm³ = (2πrh)cm²

r =2cm

as, we found that radius of cylinder is, 2cm

so the diameter of cylinder is, 4cm
