<PRE><B>Question 387344</B>
 What is the exact circumference of a circle with a diameter of 13 inches? 
26p inches 
6.5p inches
13p inches 
42.25p inches
169p inches 
I was doing 13*3.14=40.84 but as you can see this is not one of my selections so I am not sure where I am going wrong.
------------------------
Since pi is an endless decimal form your answer
is approximate.  They want the exact answer which
is 13(pi).
They have listed that answer as 13p in you option list.

Correct answer: 13p

Question #2 want to double check this one

Find the volume of the pyramid with a rectangular base shown below
h=11in
w=12in
l=10in
---
V = (1/3)Bh
B = 12*10 = 120 in^2
h = 11
---
V = (1/3)120*11 in^3
V = 40*11
V = 440 in^3

120 cubic inches 
440 cubic inches 
528 cubic inches 
336 2/3 cubic inches
1320 cubic inches 

11*12*10=1320 in
