Since pi can not be written exactly as a decimal or fraction, you have two options:
1) Keep the answer as 42 pi, to have the exact value.
2) Round the number pi to the desired precision, for example 3.14, or 3.1416, then carry out the multiplication.

C=Pi times D. 42=Pi times D. D= 42/Pi Pi//\\//3.141593 Diameter= about 13.37
42
4 cm because pi*42 = 16 pi cm2
The answer depends on what the question is!
It would be pi x 42 feet
C=Pi times D. 42=Pi times D. D= 42/Pi Pi//\\//3.141593 Diameter= about 13.37
42
42/pi ie 13 feet 4½ inches, assuming pi to be 3.14
4 cm because pi*42 = 16 pi cm2
the same as pi squared, which is 9.86960440109
The answer depends on what the question is!
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
It is pi*42 = 131.9 inches approx.
It would be pi x 42 feet
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter
circumference=pi circumference=pi circumference=pi
