We  know that

the perimeter of a circumference=2*pi*r

<span>If the perimeter of a sector is 4 times its radius, then the arc measure of the sector is (4r-2r)----> 2r
so
if 2*pi radians (full circle) has a length------------------> 2*pi*r
 X radians -------------------------------------------> </span>2*r  (the sector)<span>
X=2*r*(2*pi)/(2*pi*r)-----> x=2

the answer is
2</span>

Global mean temperature was changing the most rapidly in 2005. How quickly was the temperature changing in 2005
AysviL [449]

The temperature was changing at a rate of 2.925 degrees Celsius in 2005

<h3>How to determine the rate in 2005</h3>

From the graph (see attachment), we have the following ordered pair

(x,y) = (5,14.625)

The above means that, the temperature in 2005 is 14.625 degrees Celsius

So, the rate in 2005 is:

Rate = \frac{14.625}{5}

Rate = 2.925

Hence, the temperature was changing at a rate of 2.925 degrees Celsius in 2005

65*64*63! / 2 * 63! =
65*64 / 2 =
