Answer:
A is approximately 201 cm^2
Step-by-step explanation:
The diameter of the circle is 16 so the radius is 1/2 of the diameter
1/2 * 16 = 8
The area of the circle is
A = pi r^2
A = 3.14 * 8^2
A =200.96 cm^2
A is approximately 201 cm^2
Using the washer method, the volume is given by the integral

where 3 - 1 = 2 is the distance from <em>y</em> = 3 to the axis of revolution, and similarly (1 + sec(<em>x</em>)) - 1 = sec(<em>x</em>) is the distance from <em>y</em> = 1 + sec(<em>x</em>) to the axis. The integrand is symmetric about <em>x</em> = 0, so the integral "folds" in on itself, and the integral from -π/3 to π/3 is twice the integral from 0 to π/3.
So the volume is

Answer: There will be two different ways of doing so.
Step-by-step explanation:
Since we have given that
Total number of rocks =38
If we want to groups of 10 rocks or as single rocks then there are 2 different ways ;
<u>Case I:</u>
if we group into 10 rocks
there will be four sets in which Ist set contains 10 rocks
Second set contains 10 rocks
Third set contains 10 rocks
and Fourth set remains with 8 rocks only.
<u>Case II:</u>
if we group as single rocks .
There will be 38 sets .
D is the correct answer
