If a circular cross-section with a center at (1, 1) and radius of 1 is rotated about the line y = 1, what will be the resulting
three-dimensional object?
1 answer:
Answer:
sphere (see the explanation)
Step-by-step explanation:
we know that
When you will rotate a circle about its diameter, you will obtain a sphere.
The radius of the sphere will the same as that of the circle.
In this problem
The circle is rotated about the line y=1
The line y=1 passes through a diameter of the circle
The equation of the circle is
see the attached figure to better understand the problem
so
The circle is rotated about its diameter
therefore
The resulting three-dimensional object will be a sphere with radius of 1

Answer:
Answer: Third option is the right answer.
Step-by-step explanation:
First we the write the expression
Now teacher says that the product of these polynomials will result in the sum of
Now the teacher ask if we put the value of a = 2x and b = 1 then what will be the expression look like.
=
So third option is looking like our expression.
Answer:
112in²
Step-by-step explanation:
Formulas: V = , V = lwh
Sub: v =
Solve: 32
Sub: v = 4 x 4 x 5
Solve: 80
V = 80 + 32
V = 112
<u>The total volume of the figure is 112in²</u>
