I believe #2 would be the best answer. Either that or #1.
Answer:
The rate change of volume of the cylinder is
cubic inch per second.
Step-by-step explanation:
Given that the radius of right circular cylinder is
and its height is
where t is time in second and the dimension are inches.

The base area of the cylinder is A= 



Differentiating with respect to t


Differentiating with respect to t


The volume of cylinder is V= Ah
∴V= Ah
Differentiating with respect to t




The rate change of volume of the cylinder is
cubic inch per second.
Answer:
0.333333
Step-by-step explanation:
Answer: The value of ∠CBD is 98°.
Step-by-step explanation:
Since we have given that
m∠CBD=4x+52∘
and
m∠ABC=8x−10∘
As we know that they are linear pairs.
As we know that a linear pair is a pair of adjacent angles when two lines get intersected by a line say BC.
So, Sum of linear pair is supplementary.

So, m∠CBD = 4x+52=4(11.5)+52=98°
Hence, the value of ∠CBD is 98°.
