Find the circumference of a circle that has a diameter of 4 m..

Mathematics
1 answer:
Gnesinka [82]3 years ago
6 0

If diameter = 4,

then radius = 4/2 = 2m.

Formula for the Circumference of a Circle = 2\pir

2\pir = 2 x 22/7 x 2

2 x 22/7 x 2 = 4 x 22/7 = 88/7

= 12.5714286 cm.

It can be also be rounded up into 12.6 cm.

So, the Circumference of the Circle is 12.6 cm or 12.5714286 cm.

Find the distance between the points (-10, -9) and (-7, -1).
QveST [7]

Answer:

Distance: 8.5440037453175

Step-by-step explanation:

Distance: 8.5440037453175

Steps:

Distance (d) = √(-7 - -10)2 + (-1 - -9)2

= √(3)2 + (8)2

= √73

= 8.5440037453175

Slope and Angle:

ΔX = -7 – -10 = 3

ΔY = -1 – -9 = 8

Slope (m) =  

ΔY

ΔX

=  

8

3

= 2.6666666666667

θ =  

arctan( ΔY )

ΔX

= 69.443954780417°

Equation of the line:

y = 2.6666666666667x + 17.666666666667

or

y =  

8 x

3

+  53

3

When x=0, y = 17.666666666667

When y=0, x = -6.625
