Answer:
A = 28.3 cubic inches; P = 20.1 inches
Step-by-step explanation:
<em>Looks like 3/4 of a full circle</em>
<em>The area of a circle is calculated with the formula: </em>
<em>Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.</em>
<em>The radius is given as 3 inches</em>
Area =
cubic inches = 28.3 cubic inches
------------------------
<em>Perimeter is calculated with </em>
<em>.</em>
<em>But this is 3/4 of a circle with an additional two 3-inch sides</em>
Perimeter =
+ 2(3) = 14.1 + 6 = 20.1 inches
Answer:
(3, -4)
Step-by-step explanation:
For this problem you just need to find the distance between each of the x values and each of the y values.
The difference between -2 and -7 (-7 - -2) is -5, so the x coordinate of point B should be 3 (-2 - -5).
The difference between 2 and -1 (2 - -1) is 3, so the y coordinate of point B should be -4 (-1 - 3).
Answer:
No, because there is only one set of congruent angle
Step-by-step explanation:
X^2+(y-2)^2=4 is a circle centered at (0,2) with radius 2.
Thus, when you rotate it around the y-axis (around x=0),
you get a sphere with radius 2.
((which is centered at (x,y,z)=(0,2,0), if you take y to be
the vertical axis ... not that you need to know this for volume))
--------------------------------------------------------------
Volume of a sphere formula: V = (4/3)πr^3.
