Will give BRAINLIEST The liquid in a bulb thermometer falls
1.1 cm. Calculate the liquid's change
in volume if the inner radius of the
tube is 6.5 X 10^-3 cm.

Please show work

Step 1

V=\piπ(r^{2}r  

2

)\cdot⋅h

Volume of a cyclinder

Step 2

2 of 4

V=\piπ((6.5\cdot10^{-3}cm)^{2}(6.5⋅10  

−3

cm)  

2

)\cdot⋅1.1cm

Plug in values

Step 3

3 of 4

1.46006\cdot10^{-4} cm^{3}

1.46006⋅10  

−4

cm  

3

After simplify the equation from step 2 and using significant figures.

Result

4 of 4

1.5\cdot10^{-4} cm^{3}

1.5⋅10  −4 cm  3

Step-by-step explanation:

So i looked this up... I hope this helps!

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

⭐dhruv⭐

b is the correct answer
