Answer :
- Volume of cylinder = 43.6577 cm³
- It is to be rounded off to significant digits = 43.7cm³
Given :
- The length and the radius of a cylinder measured with slide callipers are found to be 4.54cm and 1.75cm
To find :
- Volume of cylinder
Solution :
To find the volume of cylinder we must use the formula of volume of cylinder
Given,
- Length of cylinder = 4.54 cm
- Radius of cylinder = 1.75 cm
We know that
- Volume of cylinder = πr²l
Where,
- l is length of cylinder
- r is radius of cylinder
》Volume of cylinder = πr²l
》Volume of cylinder = π × 4.54 × (1.75)²
The minimum number of significant digits on a particular term is 3 so , result must should have three significant digits and rounded off
》Volume of cylinder = 3.14 × (1.75)² × 4.54
》Volume of cylinder = 3.14 × 1.75 × 1.75 × 4.54
》Volume of cylinder = 43.6577 cm³
Now, It is to be rounded off to significant digits = 43.7cm³

Answer:
43.65 cm
Explanation:
lenght of cylinder= 4.54cm
radius of cylinder= 1.75cm
we know that
volume of cylinder= πr^2h
the value of π = 22/7
(22/7)*1.75*1.75*4.54
43.65cm
