Question

The length and the radius of a cylinder measured with a slide callipers are found to be 4.54 cm and 1.75 cm respectively . Calculate the volume of the cylinder .

Answer 1

Thanks for asking the question!

ANSWER::

Given:-
Cylinder measurements
Length = l = 4.54 cm 
Radius = r = 1.75 cm
Volume of cylinder = πr²l = 3.14 x 1.75 x 1.75 x 4.54 = 43.6577 cm³

Now , we have to round off to 3 significant digits , V=43.7 cm³

Hope it helps!

Answer 2

$Length=4.54 cm \\ radius =1.75 cm \\ Volume \: of \: cylinder = πr^{2} l \\ =3.14×(1.75)^2 × \: 4.54 \\ = 3.14 \times 1.75 \times 1.75 \times 4.54 \\ = 43.6577 \\ = 43.7cm ^{3}$
