The circumference of a circle is 4 pie centimeters. What is the radius?

r=2

Step-by-step explanation:

The circumference of a circle is : P = 2πr... r : the radius and  P= 4π

so :  2πr = 4π

divide by :  2π  you have :  r = 2

2cm

Step-by-step explanation:

Circumference of a circle =2pir

Circumference given=4pi

R=?

Substitute the values

2pir=4pi

Pi cancel pi

2r=4

R=4/2

R=2

Radius of the circle is 2cm

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
