Question

The curved surface area of a cylinder is 1,320 cm2 and its base has a radius of 10.5 cm. Find the height of the cylinder.​

Answer 1

Answer:

ans.20 cm

Step-by-step explanation:

CSA of cyclinder= 1320

Radius=10.5cm

CSA=2πrh

1320=2×22/7×10.5×h

60=2×1.5×h

60=3.0×h

h=20 cm

Height of the cylinder=20cm

I hope this answer is helpful.

Answer 2

Answer:

Height = 20

Step by step explanation :-

Given , C.S.A = 1320cm^2, radius = 10.5 cm

Let height be h.

C.S.A = 2π rh

1320 = 2× 22/7 × 10.5 × h

1320 = 44/7 × 10.5 × h

1320 = 44 × 1.5 × h

h = 1320/66

h = 20
