Answer:
V = 200 π
Step-by-step explanation:
x = 5√y , x = 0 , y = 4
<u>Determine the volume of the solid V</u>
when x = 0 y = 0
we can calculate the volume of the solid by applying the washer method
V = π ₀⁴∫ [ 0 + ( 5√y )^2 ] dy
= π ₀⁴∫ [ 0 + ( 25(y) ) ] dy
V = π [ 0 + 25/2 ( y^2 ) ] ⁴₀
V = π [ 25/2 ( 16 ) ]
= 200 π
Answer:
870
Step-by-step explanation:
Assuming you mean
30
Using the definition
n
= 
where n! = n(n - 1)(n - 2) ..... 3 × 2 × 1
Then
30 = 
= 
Cancel the terms 28(27)... on numerator/ denominator, leaving
30 = 30 × 29 = 870
