Question

Adventure camps are the perfect place for
children to practice decision making for
themselves without parents and teachers guiding
their every move.
Some students of a school reached for adventure
d=7 cm
at Mukteshwar. At the camp, the waiters served
h=10.5 cm
d = 7 cm
some students with a welcome drink in a cylindrical glass and some students in a
hemispherical cup whose dimensions are shown above.
After that they went for the jungle trek. The jungle trek
was enjoyable but tiring. As dusk fell, it was time to take
shelter. Each group of four students was given a canvas
Area = 551 m
/r= 7 m
of area 551 m2. Each group had to make a conical tent
to accommodate all the four students. Assuming that all
the stitching and wasting incurred while cutting, would amount to 1 m², the students put
the tents. The radius of the tent is 7 m.
Refer to Glass and Cup
(i) The volume of cylindrical cup is
(6) 7415.5 cm (c) 384.88 cm3 (d) 404.25 cm?
(a) 295.75 cm3

Answer 1

Option d) 404.25 $cm^{3}$ is the answer.

Given:

Diameter of cylindrical glass d = 7cm

Height of cylindrical glass h = 10.5cm

Diameter of hemispherical cup d = 7cm

To find:

The volume of the cylindrical cup

Solution:

We know that the formula of the volume of a cylinder is

$V = \pi r^{2}h$

$V = \pi \frac{d^{2} }{4}h$

$V = \pi \frac{49}{4}* 10.5$

$V = 404.25 cm^{3}$

Hence the Volume of the cylindrical cup is 404.25 $cm^{3}$.
