Question

The C.S.A of a cylinder is 4400cm sq. And the circumference of its base is 110cm. Find H and V

Answer 1

$\huge{ BEST ANSWER }$

$\huge{ Let the radius=R  and height =H  Curved surface area of the cylinder, S=2πRH= 4400 cm sq  Circumference of the base, C=2πR =110 cm  2πRH= 4400 and 2πR= 110  Hence H=2πRH/2πR =4400/110=40 cm  Since circumference, C=2πR =110  and R= C/2π =110/2π=55/π cm  Volume, V=πR²H =π(55/π)²×4=38515.496 cm²}$
