Question

C S.A of cylinder is 7.04 Radius = 0.28 find the height ? ​

Answer 1

Step-by-step explanation:

r = 28 cm and TSA =7.04 m²

r = 0.28 m

$\red{\underline{\bold{Solution \colon}}}$

Solution:

2πr(h+r) = 7.04

2π(.28)(h+.28) = 7.04

h+0.28 = 7.04÷(2π×0.28)

h+0.28 = 4.001

h= 4.001-0.28

h=3.712 m

Answer 2

Given

• Curved surface area of cylinder = 7.04 cm²
• Radius of cylinder = 0.28 cm

To find

• Height of cylinder

Solution

• Curved surface area of cylinder =  2πrh

Substitute the values and find the height :-

• 2πrh = 7.04
• 2×22/7×0.28×h = 7.04
• 44/7×0.28×h = 7.04
• 1.76h = 7.04
• h = 7.04/1.76
• h = 4

Hence, the height of cylinder is 4 cm
