Answer:
The outer diameter of the shaft to 2s.f is 12.65cm
Step-by-step explanation:
We know that the expression for the area of a circular cross section is
A=
given data
area of cross section=
bore diameter d= 8cm
from the area of cross section we can solve for the outer diameter D
solving for D we have
Answer:q=575
Step-by-step explanation:
Multiply by 3 on both sides
Divided both sides by 2
