Question

heya!!

How many litres of milk can a hemispherical bowl of diameter 10.5 cm. hold?

spammers be away please!

thank you :D

Answer 1

Given diameter of the hemispherical bowl = 10.5cm

radius of the hemispherical bowl (r) = 10.5/2 = 5.25 cm

volume = (2/3)*Π*(5.25)3

            = (2*3.14*5.25*5.25*5.25)/3  
 
(Π = 3.14)

            = 2*3.14*5.25*5.25*1.75

           = 302.91 cm3

           = 303 cm3 

Now 1000 cm3 = 1 litre

So  303 cm3 = 303/1000 = 0.303 litres

So total amount of milk = 0.303 litres

$<b>$
Radius of Hemisphere = Diameter/2

= $\bold{ \frac{10.5}{2} = 5.25}$

$\bold{volume \: of \: hemisphere = \frac{2}{3}\pi \: r {}^{3} }$

$\bold{ \frac{2}{3} \times \frac{22}{7} \times 5.25 \times 5.25 \times 5.25} \\ \\ \bold{303.1875 \: \: cm {}^{3} } \\ \\ \bold{303.1875 \times \frac{1}{1000} \: litre } \\ \\ \bold{0.3031875 \: \: litre} \\ \\ \bold{ \therefore \: 0.303 \: litre \: (approx.)}$
