Answer: The answer is 972.
Step-by-step explanation: The formula for the volume if a cylinder is πr2h and the radius is 9 and to the second power is 81. So then the radius multiplied by the height (which is 12) is 972 which is the answer.

hello :
restrictions on x for xsquared -1/x-1 is : x-1 ≠0
Answer:
Let a be the first term.
The sum is a1−r=33.25.
The second term is ar=7.98, so a=7.98/r.
Putting these together, 7.98/r(1−r)=33.25 or r(1−r)=0.24=0.6×0.4.
If the answer doesn't jump out at you from there, you could solve for r with the quadratic formula.

Step-by-step explanation:
<u>We know that:</u>
- Given expression: 7xy - x²t + 4xy + 5x²t
<u>Solution:</u>
- 7xy - x²t + 4xy + 5x²t
- => 11xy - x²t + 5x²t
- => 11xy + 4x²t
Hence, the simplified expression is 11xy + 4x²t.
