Given:
A circle with diameter 9 cm.
To find:
The area of the circle.
Solution:
The area of a circle is:
...(i)
Where r is the radius.
We know that, the diameter of a circle is twice than its radius.
The diameter of the given circle is 9 cm.
Substituting 
in (i), we get
Therefore, the area of the given circle is 63.6.
Answer:
False
Step-by-step explanation:
Answer:
1 is the degree of 7x because according to alzebra if the variable have nothing power then that has power 1
As given arithmetic sequence is :-
-17 , -13 , -9
So, here we have to find a12
a ( 1st term ) = -17
d ( common difference) = a2 - a1
d = -13 -(-17)
d = 4
nth place = a12
Now we know that to find any term we apply formula :-
an = a + (n-1)d
So putting Values in above mentioned formula :-
a12 = -17 + ( 12-1) 4
a12 = -17 + (11)4
a12 = -17 + 44
<h3>a12 = 27 </h3>
Hope it helps
