Answer:
the area of the circle is
.
Step-by-step explanation:
We have,
Circumference of a circle is 3π cm
Formula of circumference of a circle is given by :

r is radius of circle

Area of a circle is given by :

So, the area of the circle is
.
Answer:
x=6
Step-by-step explanation:
First, add 1 on both sides
4x + 5 = 5x -1
+1 +1
4x+6 =5x
Then, subtract 4x on both sides
4x+6 =5x
-4x -4x
6=x
So, x equals 6
Hope this helps! :)
'Tis a Binomial. if it were a monomial, there would be no operator between 6x^2 and 2xy^2
<em>AC bisects ∠BAD, => ∠BAC=∠CAD ..... (1)</em>
<em>thus in ΔABC and ΔADC, ∠ABC=∠ADC (given), </em>
<em> ∠BAC=∠CAD [from (1)],</em>
<em>AC (opposite side side of ∠ABC) = AC (opposite side side of ∠ADC), the common side between ΔABC and ΔADC</em>
<em>Hence, by AAS axiom, ΔABC ≅ ΔADC,</em>
<em>Therefore, BC (opposite side side of ∠BAC) = DC (opposite side side of ∠CAD), since (1)</em>
<em />
Hence, BC=DC proved.
