<em><u>Solution:</u></em>
<em><u>Given that:</u></em>

We have to find the value of expression
We know that,

Therefore,

We know that,

Similarly,

Thus value of 2 to the power of negative 3 times by 3 to the power of negative 2 is 0.013889
Answer:
485.9 mm³
Step-by-step explanation:
The volume of a sphere is 4/3 π r³. So the volume of a hemisphere is half of that:
<h3>V = (2 / 3) π r³</h3>
V = 128π/3
The formula for the volume of a cylinder is V = Bh or V = πr²h .
The radius of the cylinder is 4mm and the height is 7mm
Substitute 4 for r and 7 for h in the formula V = πr²h .
<h3>V=π(4)²(7)</h3>
V = 112π
Since the figure is made up of a hemisphere and cylinder so volume will be sum of these two shapes
<h3>V = 128π/3 + 112π</h3>
= 485.9 mm³
The multiplicative inverse of -2/5 is -5/2
