Answer 1

Step-by-step explanation:

As we know 1500 = 1.5L

So,Mug Volume is 1.5 and in 270 Litres ,It will be 270÷1.5

Then,

270÷1.5

=180

180 Mugs

Answer 2

Answer:

Given that, the radius of a hemispherical bowl is 2 m.

To find out: The amount of water, in litres, that the bowl can contain.

We know that, volume of a hemisphere =32πr3

=32×722×2×2×2[∵ π=722]

=21352

=16.7619 m3

Now, we know that 1 m=100 cm

∴ 1 m3=(100)3 cm3

Hence, 16.7619 m3=16.7619×(100)3 cm3

=16.7619×1000000 cm3

=16761900 cm3

Given that, 1000 cm3=1 litre

∴ 16761900 cm3=100016761900 litres

=16761.9 litres
