How do you find the radius and diameter with the circumference

Mathematics
1 answer:
Levart [38]2 years ago

Ok

relation of diameter to radius
2 radius=1diameter
radius=1/2 diameter
2r=d
d/2=r


circumfernce=2pir
since 2r=d
circumference=2d

so
c=pid=2pir

so if ou have circunference and you want to find diameter and radius
c=pid
divde both sides by pi
c/pi=d

c=2pir
divide both sides by 2pi
c/(2pi)=r


so
r=c/(2pi)
d=c/pi

Linear equation: -1
Anika [276]

Answer:

The right answer is:

the addition property of equality and then the division property of equality

Step-by-step explanation:

Given equation and steps to solve it are:

Step 1: –3x – 5 = 13

Step 2: –3x = 18

Step 3: x = –6

In step two, -5 has to be removed from left hand side of the equation so additional property of equality will be used i.e. adding 5 on both sides

Similarly in the third step, to remove -3 with x , division property of equality will be used i.e. dividing both sides by -3

Hence,

The right answer is:

the addition property of equality and then the division property of equality
