The circles are identical. What is the circumference of each circle? Circle 1: radius of 2x; Circle 2: diameter of 2x+3. A. 3/2
Delicious77 [7]

Answer:

C=6π

Step-by-step explanation:

It is given that, two circles are identical. The radius of first circle is 2x and the diameter of other circle is 2x+3.

If identical, it means that the radius of both circles are same i.e.

2x=\dfrac{2x+3}{2}\ \ (\because\ r=\dfrac{D}{2}, d=\text{diameter})\\\\4x=2x+3\\\\2x=3\\\\x=1.5

Radius of both circles is 2(1.5)=3

The circumference of a circle is given by :

C=2\pi r\\\\C=2\pi (3)\\\\C=6\pi

So, the circumference of each circle is 6π.

x^2 = 5184 + 4225

x^2 = 9408

x = 97 m.

How many 1/10s in 2 3/5
Umnica [9.8K]

It'd be clearer if you'd write:  "How many tenths are there in 2 3/5?"

2 3/5        13/5

---------- = ---------- = 26

(1`/10)        1/10

There are 26 tenths in 2 3/5.
