Question

find the height of a right circular cylinder whose curved surface of 616cm2 and diameter of the base is 14 cm​

Answer 1

Answer:

14 cm

Step-by-step explanation:

d=14cm

r=d/2=7cm

CSA=616cm²

2πrh=616cm²

$2*\frac{22}{7}*7*h=616cm^{2}$

$h=\frac{616}{22*2}$

h = 14cm

Answer 2

Given :-

• CSA of cylinder = 616 cm²
• Diameter of base = 14 cm

To Find :-

Height

Solution :-

We know that

Radius = Diameter/2

⇒ Radius = 14/2

⇒ Radius = 7 cm

CSA of cylinder = 2πrh

⇒ 616 = 2 × 22/7 × 7 × h

⇒ 616 = 44 × h

⇒ 616/44 = h

⇒ 14 = h

Hence,

The height of cylinder is 14 cm
