Question

the sum of the radius of the base and height of a solid cylinder is 37cm.if the total surface area is 1628cm square find r and h​

Answer 1

Answer:

Total surface area of cylinder = 2πr² + 2πrh = 2πr (r+h)

1628 =  2πr (r+h) =  2πr (37)

1628/37 = 2πr

2πr = 44

2r = 44/ (22/7) = 14

r = 7 cm

h = 37 - 7 = 30 cm
