C is the correct answer. An equilateral triangle is a type of triangle.
Answer:
34191.7πin³/sec
Step-by-step explanation:
Volume of circular come = 1/3pi x r² x h
When we differentiate this formula we have
dv/dt = 1/3π[r²dh/dt + 2rhdr/dt]
We have the following information
r = 138
H = 143 inch
dr/dt = 1.4
dh/dt = -2.8
When we plug into the formula
1/3π[130² x -2.8 + 2x138x143x1.4]
= 34191.7πin³/sec
0+1=1
1-0=1
1x1=1
1/1=1
1 is in everything if this didnt help tell me
Answer:
It is totaly based on the diagram
Assuming that the x is not part of the ^-1 the range would be
[0,π/2) U (π/2,<span>π]</span>
