Answer:
Jude is not correct
Step-by-step explanation:
The volume of a square pyramid is given as:

where a = base edge and h = height
Hence, the volume of the square pyramid with base edge of 7 in and height of 7 in is:

V =
≅ 
The volume of a cylinder is given as:

where r = radius and h = height
Hence, the volume of a cylinder with radius of 7 in and height of 7 in is:

V =
≅ 
Since their volumes are not equal, Jude is not correct.
4.8 x 10^-2
You can do this without a calculator
Explanation:
(3.2 x 10^-5) x (1.5 x 10^3)
First, you multiply 3.2 by 1.5 to get 4.8
Next, you add the exponents together: -5 + 3 = -2
Now, put everything into one answer (the 10 stays the same): 4.8 x 10^-2
