Question

Find height of a cylinder whose base of diameter 7 cm and curved surface area equal to 44 centimetre square

Answer 1

I hope it will help you...

Answer 2

HELLO DEAR,

given that:-

diameter=7cm

RADIUS=diameter/2=7/2cm

height of CYLINDER = h

Surface Area (CSA) of Cylinder = 44cm²
we know that;-

Surface Area (CSA) of Cylinder = 2πrh.


$2 \times \frac{22}{7} \times \frac{7}{2} \times h = 44 \\ = > h = \frac{44 \times 2 \times 7}{22 \times 7 \times 2} \\ = > h = 2cm$

I HOPE ITS HELP YOU DEAR,
THANKS
