.The curved surface of cylinder is 484 cm^2 and height is 5.5 cm. Find its radius.
2 answers:
Answer:
r=14cm
Step-by-step explanation:
Curved Surface area of a cylinder=484cm²
Height=5.5cm
r=?
Curved Surface Area=2πrh
484=2×3.142×r×5.5
484=34.56r
r=484/34.56
r=14cm
Answer:
radius= 14
Step-by-step explanation:
curved surface area of cylinder = 484
height = 5.5
C.S.A = 2πrh
or, 484 = 2×22/7×r×5.5
or, 484×7 = 2×22/7×5.5×r
or, 3388 = 242×r
or, 3388/242 = r
or, 14 = r
