When multiplying terms with exponents, just add the exponents together.
You have x^7 and x^4, so 7 +4 = 11
Y^2 and Y^5 = 2+5 = 7
so it would be -20x^11 y^7
The answer is A.) a=11, b=7

Step-by-step explanation:
Answer:
So, The possible values of h and r are
1. r = 3 , h = 3
2. r = 1, h = 27
3. r = 2, h = 6.75
Step-by-step explanation:
P.S - The exact ques is -
As we know that Volume of cone , V = 
As given,
V = 
⇒
So,
The possible values of h and r are
1. r = 3 , h = 3
2. r = 1, h = 27
3. r = 2, h = 6.75
In Case I-
When r = 3, h = 3
(3)² ×3 = 9×3 = 27
Satisfied
Case II-
r = 1, h = 27
(1)²×27 = 1×27 = 27
Satisfied
Case III-
r = 2, h = 6.75
(2)²×6.75 = 4×6.75 = 27
Satisfied
The answer would be $23.75
