Answer:1411.3 cm

Step-by-step explanation:

circumference = 8871 cm

radius=?

pi=22/7

c=2 pi r

8871 =2 x 22/7 x r

8871 x7 =2 x 22 x r

62097=44r

r=1411.3 cm

36 erasers shared in the ratio 6 is 6 (36/6)
So the is 6 in 1 ratio.
6 x the ratio 2 is 12
So there are 12 pencils

const2013 [10]

Hello.

-50 <7k +6

-56 < 7k

-8 < k

k > -8 Your first answer is done.

7k +6 <-8

7k<-14

k < -2 There's your second answer.

For graphing, remember these rules:

1). Left to right-- Smaller to bigger numbers.

2). < or > is an unfilled/ empty dot.

3). greater than or equal/ less than or equal to is a filled dot.

(X+2)^2+(y-4)^2=16 what is the radius
Sholpan [36]

Answer:

The radius = 4

Step-by-step explanation:

considering the equation

\left(x+2\right)^2+\left(y-4\right)^2=16

As the standard form of the circle is

\left(x-h\right)^2+\left(y-k\right)^2=r^2

Match the values in this circle to those of the standard form.

  • The variable  r represents the radius of the circle,  
  • h represents the x-offset from the origin, and  
  • k  represents the y-offset from origin.

\mathrm{Rewrite}\:\left(x+2\right)^2+\left(y-4\right)^2=16\:\mathrm{in\:the\:form\:of\:the\:standard\:circle\:equation}

\left(x-\left(-2\right)\right)^2+\left(y-4\right)^2=4^2

\mathrm{Therefore\:the\:circle\:properties\:are:}

\left(h,\:k\right)=\left(-2,\:4\right),\:r=4

Therefore, the radius = 4
