Question

A container is in the form of a cylinder closed
at one end by a hemisphere. The radius of the
cylinder is 8.4 cm & the total height of the
Container is 52.8 cm. How many litres of petrol
can this container hold?
​

Answer 1

hey mate

here is the answer...

Answer:

the height of the cylinder=52.8 cm -8.4 cm

=44.4 cm

volume of the solid=volume of the cylinder+volume of the hemisphere

volume of the solid=πr²h+2/3πr³

volume of the solid=πr²(h+2/3r)

volume of the solid=π(8.4)²(44.4+2/3*8.4)

volume of the solid=π*70.56*(44.4+5.6)

volume of the solid=π*70.56*50

volume of the solid=22/7*70.56*50

volume of the solid=11088 cm³

since 1cm³=1/1000 L

thus,

volume of the solid=11088/1000 L

volume of the solid=11.088 L
