Outer diameter= 1/36*2+1/6
= 8/36
= 1/4 is the outer diameter, NOT 1/3 (sorry I had answered this question earlier)
This is the concept of transformations, given that ABC was rotated it implies that it retained it's original dimensions. This means that ABC is proportional to EFD. Therefore, given that EF=4.2 cm, DF=3.6 cm and DE=4.5 cm. The CB=FD=3.6 cm
Answer:
a=21
b=25/2
c=77/2
Step-by-step explanation:
from eq 1
a+4=2b => a=2b-4
substituting value of a in eq 2
c-5=a+b => c-5=2b-4+b => c =3b+1
now, substituting value of a and c in eq 3
a+b+c=72 => 2b-4+b+3b+1 =72 => 6b-3=72 => b= 75/6 => b=25/2
substituting value of b in :
c=3b+1 ( you will get c )
then substitute value of b in :
a=2b-4 ( to get a)
It will be400 divided by 6.88
