Answer: 10.6
Step-by-step explanation: it has a .3% increase each time, therefore it would be D. 10.6
Answer:
1.1783
Step-by-step explanation:
The attached picture shows a cross section of the cylindrical shell that it is convenient to use as a differential of the volume. The radius from the center of revolution is (1-x), so the circumference of the shell is 2π(1-x). Of course, its height is tan(x), so the differential of volume is ...
dV = 2π(1-x)tan(x)
The indefinite integral does not have a nice closed-form solution, but it can be easily integrated numerically from x = 0 to 1 by most scientific and graphing calculators. The attached shows the volume to be about 1.1783 cubic units.
A soccer ball is an icosahedron with curved faces that is why it can be regarded as spherical. The volume of a sphere is calculated through,
Vs = 4<span>πr^3/3
where Vs is the volume and r is radius. From the given, 8.65 in is the diameter which is 4.325 in in radius.
Vs = 4</span><span>π(4.325^3)/3 = 338.88 in cubed.
Thus, the volume of the ball is 338. 88 in cubed. </span>
