Question

given the c s a of aright circular cylinder 87 cm2 and its base diameteras 2 cm find the height of the cylinder​

Answer 1

Step-by-step explanation:

CSA of a cylinder is 2πrh

Given d=2cm so r=1cm

CSA = 87cm²

Thus by putting values

87=2×π×1×h

87=2×3.14×1×h

87=6.28×h

h=87/6.28

h=8700/628

h=13.85 cm (approx.)
