384π cm³ ( first one in list )
Calculate the volume (V) of the cone using the formula
V = 
πr²h ( r is the radius and h the height )
here r = 12 and h = 8
V = × 12² × 8 = 384π cm³ ← exact value
We can write this as the difference of squares:
(5b⁸+8c)(5b⁸-8c)
To write as the difference of squares, take the square root of each term first:
√25b¹⁶ = 5b⁸; √64c² = 8c
Now we write this as a sum in one binomial and a difference in the other:
(5b⁸+8c)(5b⁸-8c)
Answer:
i believe it’s graph A
Step-by-step explanation:
Total cost of books was 15 + 10 or 25. With the 50 % discount on the $10 book, the total is now $20. The total cost was reduced by (B) 20%.
$5 off the $25 price is a 20% discount.
