Since the formula for the area of a circle is Pi x r squared, the area would be 81 x Pi (you teacher may want you to use Pi as 3.14 or put it in your calculator).
The answer is strong negative. Hope this helps
You would just have to isolate for x
so it would simply become
-1.56/-7.8
= 0.2
Answer with explanation:
The given statement is which we have to prove by the principal of Mathematical Induction

1.→For, n=1
L H S =2
R H S=1
2>1
L H S> R H S
So,the Statement is true for , n=1.
2.⇒Let the statement is true for, n=k.

---------------------------------------(1)
3⇒Now, we will prove that the mathematical statement is true for, n=k+1.

Hence it is true for, n=k+1.
So,we have proved the statement with the help of mathematical Induction, which is

In a triangle, the midsegment is parallel to and half of non-intersecting side.
