V=pir^2h
Divide both sides by h.
v/h= pir^2
Multiply both sides by v.
h=pir^2*v
I hope this helps!

Answer:
it is 8 thousandths of an inch.
Step-by-step explanation:
3/4 of an inch is .75 of an inch. divide that by 90 an you get 0.008ths of an inch.
Answer:
f(1) = 8, f(2) = 7
Step-by-step explanation:
Function: f(x)= 9-x
f(1) = 9-1 = 8
f(2) = 9-2 =7
Answer:
(1) e2x [ (2x -1 )cot x – x cosec2x]/x2
(2) e2x [ (2x +1 )cot x – cosec2x]/x2
(3) e2x [ (2x -1 )cot x + cosec2x]/x2
(4) none of these
Solution:
Given y = e2x cos x /x sin x
Differentiate w.r.t.x
Use quotient rule
dy/dx = [x sin x (d/dx)e2x cos x – e2x cos x (d/dx) x sin x]/ (x sin x)2
= [x sin x (e2x ×2× cos x – e2x sin x ) – e2x cos x ( sin x+ x cos x)]/ (x sin x)2
= [ x 2 sin x cos x e2x – e2x x sin2 x – e2x cos x sin x – e2x x cos2 x]/ (x sin x)2
= [ x sin 2x e2x – x e2x(sin2x+cos2x) – e2x sin x cos x]/(x sin x)2
= [ x e2x sin 2x – x e2x – e2x sin x cos x]/(x sin x)2
= [ 2x e2x cot x – x e2x cosec2 x – e2x cot x]/x2
= e2x [ 2x cot x – x cosec2 x – cot x]/x2
= e2x [ (2x -1 )cot x – x cosec2x]/x2
Hence option (1) is the answer
Answer:
Step-by-step explanation:

The rule that governs this situation is the average of arc d and 94 = the angle where the chords cross.
Givens
Arc 1 = 94
Arc2 = d
interior angle = 75
Formula
(d + 94)/2 = interior angle/1
Solution
(d + 94)/2 = interior angle/1 Cross Multiply
1*(d + 94) = 75 *2 Combine
d + 94 = 150 Subtract 94 from both sides
d + 94 - 94 = 150 - 94 Combine
d = 56
Answer: d = 56
