The similar paperweight has a volume of 67.2 cubic cm if the height is 7 cm.
<h3>What is volume?</h3>
It is defined as a three-dimensional space enclosed by an object or thing.
As we know,
Volume = base area×height
38.4 = base area×4
base area = 38.4/4 = 9.6 square cm
A mathematically similar paperweight has a height of 7 cm.
Volume = base area×height
Volume = 9.6×7 = 67.2 cubic cm
Thus, the similar paperweight has a volume of 67.2 cubic cm if the height is 7 cm.

The value of the expression 1/√2 + π where the given parameters are π = 3.141 and √2 = 1.414 is 3.848
<h3>How to evaluate the expression?</h3>
The given parameters are
π = 3.141
√2 = 1.414
The expression to evaluate is given as:
1/√2 + π
Start by substituting π = 3.141 and √2 = 1.414 in the expressions 1/√2 + π
1/√2 + π = 1/1.414 + 3.141
Evaluate the quotient
1/√2 + π = 0.707 + 3.141
Evaluate the sum
1/√2 + π = 3.848
Hence, the value of the expression 1/√2 + π where the given parameters are π = 3.141 and √2 = 1.414 is 3.848
