Question

The curved surface area of cylinder is 1320 cm2
and its base has azadius of 10.5cm . Find the
height of cylinder.​

Answer 1

Step-by-step explanation:

CSA=1320cm^2,Base=10.5

CSA OF CYLINDER =

$2\pi \times r \times h$

1320=2×22/7×10.5/2×h(as base of cylinder is considered as diameter radius is 10.5/2)

Answer 2

Curved surface area of cylinder = 1320 cm²

Radius (r) = 10.5 cm

__________ [ GIVEN ]

• We have to find the height (h) of the cylinder.

____________________________

We know that

Curved surface area of cylinder = 2πrh

Put the known values in above formula

→ 1360 = 2 × 22/7 × 10.5 × h

→ 1360 = 44/7 × 10.5 × h

→ 1360 = 462/7 × h

→ 1360 = 66 × h

→ 1360/66 = h

→ 20.606 = h

→ h = 21 cm (approx.)

_____________________________

21 cm is the height of the cylinder.
