Question

Enter your answer in the provided box.

Carry out the following calculation, making sure that your answer has the correct number of significant figures. Use the value for

π

that has at least 7 decimal places.

V = πr²h, where r = 6.73 cm and h = 1.997 cm

cm³

Answer 1

π = 3.1415926

thus π have seven decimal place.

we have

V = πr²h

or

V = 3.1415926 * (6.73 cm)^2 * 1.997 cm

or

V = 284.1568 cem^3

this is the multiplication problem.

6.73 have three sig. Fig.

1.997 have four sig. fig

and

3.1415926 have eight sig fig.

so considering the minimum significant figures,

V = 284. cem^3 (answer)
