i know this because if youre getting 40% off, you will have to pay 60% of the total cost
so, 90 x .60 = 54
let me know if you have any further questions

Answer:
volume of sphere = 113.14inches³ or
36πinces³
Step-by-step explanation:
given the radius of a sphere = 3inches
volume of the sphere = ?
π = 3.14v 0r 22/7
recall, the formula for finding the volume of a sphere is given to be = 4/3 πr³
so,
volume of sphere = 4/3 πr³
volume of sphere = 4/3 × 22/7 × ( 3)³
volume of sphere = 4/3 × 22/7 × 27
volume of sphere = (4 × 22 × 9)/7
volume of sphere = 113.14inches³ or 36πinces³

Evaluate the indefinite integral:
Make a trigonometric substitution:
so the integral (i) becomes
Now, substitute back for t = arcsin(x²), and you finally get the result:
✔
________
You could also make
x² = cos t
and you would get this expression for the integral:
✔
which is fine, because those two functions have the same derivative, as the difference between them is a constant:
✔
and that constant does not interfer in the differentiation process, because the derivative of a constant is zero.
I hope this helps. =)
