Answer:
Step-by-step explanation:
(9*20)-(8*6) = 132 sq cm
Answer: 1960.2 cm
Step-by-step explanation:
<em>v = πr^2h</em>
v = π7.4^2(11.4)
= π54.76(11.4)
= 171.9464(11.4)
=<u> 1960.2 </u>
Answer:

Step-by-step explanation:

As the answer can be more simplified, divide both numerator and denominator by 5.

<u>Given</u>:
The 11th term in a geometric sequence is 48.
The 12th term in the sequence is 192.
The common ratio is 4.
We need to determine the 10th term of the sequence.
<u>General term:</u>
The general term of the geometric sequence is given by

where a is the first term and r is the common ratio.
The 11th term is given is

------- (1)
The 12th term is given by
------- (2)
<u>Value of a:</u>
The value of a can be determined by solving any one of the two equations.
Hence, let us solve the equation (1) to determine the value of a.
Thus, we have;

Dividing both sides by 1048576, we get;

Thus, the value of a is 
<u>Value of the 10th term:</u>
The 10th term of the sequence can be determined by substituting the values a and the common ratio r in the general term
, we get;





Thus, the 10th term of the sequence is 12.
The answer is 8(x+1)。。。。。。
