Question

If V=πr²h,find r when h =14 units and V=396(unit)³ make the formula​

Answer 1

Answer:

Radius (r) = 3units

Step-by-step explanation:

Given that,

h = 14 units; V = 396(unit)³; π = 22/7; r = ?

Now,

V = πr²h          (∵Given)

⇒ 396 = 22/7 × 14 × r²

⇒ 396/22 = 14/7 × r²

⇒ 18 = 2r²

⇒ 18/2 = r²

⇒ 9 = r²

⇒ r = √9 = 3

∴ radius (r) = 3units.
