Answer:
Step-by-step explanation:
1. Given the integral function 
, using trigonometric substitution, the substitution that will be most helpful in this case is substituting x as 
i.e 
.
All integrals in the form are always evaluated using the substitute given where 'a' is any constant.
From the given integral, 
where a = 7 in this case.
The substitute will therefore be 
2.) Given
cross multiplying
3.) Rewriting the given integral using the substiution will result into;
Answer:
yes.
Step-by-step explanation:
each x value is used once and never repeated.
To find the answer of this problem you need the formula for a cylinder.
V= pi* r^2 * h just plug in your numbers and you have the answer.
You also need to remember that diameter is just twice the radius.
The equation would be
5x= 470
470/5 = X
X = 94
Answer=94
