If the exponent is negative move the decimal to the left if it's positive move to the right
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
Answer:
152 square inches
Step-by-step Explanation:
To answer this, please look at the picture below. We can find the area by separating and combine the value of areas after calculating three values for each areas. (Notice that when we separate them, we get three rectangles which we can use the formula of width × length)
We should get 80+48+24 which add up to 152.
