Question

The volume of a cylindrical bottle of radius 2 cm is 88 cm^3then its height is

Answer 1

Answer:

Hello↪✌✌

Step-by-step explanation:

ATQ

πr^2h = 88

22/7*2*2*h = 88

h = 88*7/22*4

h = 7cm

Answer 2

$\Large\underline{\underline{\sf \orange{Given}:}}$

• Radius of bottle (R) = 2cm

• Volume of bottle (V) = 88cm³

$\Large\underline{\underline{\sf \orange{To\:Find}:}}$

• Height of bottle (h) = ?

$\Large\underline{\underline{\sf \orange{Formula\:Used}:}}$

${\boxed{\sf \red{Volume\:of\: Bottle (V)=πR^2h}}}$

$\Large\underline{\underline{\sf \orange{Solution}:}}$

$\implies{\sf 88=\dfrac{22}{7}×(2)^2×h}$

$\implies{\sf 88=\dfrac{22}{7}×4×h}$

$\implies{\sf h=\dfrac{88×7}{22×4} }$

$\implies{\sf h=\dfrac{616}{88} }$

$\implies{\sf h=7\:cm }$

$\Large\underline{\underline{\sf \orange{Answer}:}}$

${\sf \blue{\therefore Height\:of\: cylinderical\:bottle\:is\:7cm}}$
