C. 176 cm
D.
152 cm3​

Answer 1

Answer:

A)88 cm^ 3

Step-by-step explanation:

Diameter of the Cylindrical flask is 4 cm

So, radious of the Cylindrical flask is 4/2 cm = 2 cm

Height of the flask =14 cm

Half height of the flask is =14/2 Cm =7 Cm

So the volume of the water = πr^2h

=22x2x2x7/7 Cm^3

=88Cm^3

Answer 2

Answer:

A) 88 $cm^{3}$

Step-by-step explanation:

The diameter of the given cylinder d = 4cm

The radius r = 4/2 = 2cm

The height of the given cylinder is 14cm

We know that,

The volume of the cylinder V = $\pi r^{2}h$

V = $\pi \times2^{2}\times14$

V = 175.929 $cm^{3}$

Given that cylinder is half-filled with water

Therefore, the volume of water = $\frac{175.929}{2}$

                                                   = 87.96 $cm^{3}$

Hence, the volume of water in the cylinder is 87.96 $cm^{3}$
