Answer:
3.14
Step-by-step explanation:
I think what you want is the circumference of a circle with a diameter of 1
and using 3.14 for pi
so plug the numbers into the equation for circumference:
C = pi d
C = 3.14 x 1
so circumference is 3.14 based on the info in the question
Hope this helps! :)

Answer:
Pyramid B is 2.6888 times the volume of pyramid A
Step-by-step explanation:
The volume is proportional to the height, and to the square of the linear measure of the base.
Then the ratio of volumes will be ...
B/A = (592²·247)/(492²·133) = 86564608/32194512 ≈ 2.6888
Pyramid B has the greater volume by a factor of about 2.6888.
_____
<em>Additional comment</em>
The actual volumes in cubic meters will be 1/48 of the numbers we used in the ratio above.
If you recall that the side length is related to the perimeter by ...
P = 4s ⇒ s = P/4
and the volume is ...
V = 1/3s²h
Then you have ...
V = 1/3(P/4)²h = 1/48·P²h . . . . . . P²h is the number we used above
