Question

the volume of a cylinder of height 8 cm is 1232 cm³. Find its curved surface area.​

Answer 1

Answer:

first of all we find the value of r

volume of a cylinder=Πr²h

1232=22\7×r²×8

1232=176\7×r²

r²=1232×7\176

r²=49

r=7

curved surface area= 2Πrh

2×22\7×7×8

352 cm²

total surface area=2Πr(r+h)

2×22\7×7(7+8)

44(15)

660cm²
