Answer:
2.40mm
Step-by-step explanation:
In this problem. we are required to solve for the diameter of a circle.
Given data
circumference of circle c= 7.54mm
we know that the expression for the circumference is given as
c= 2πr
We can substitute our given data to solve for r
7.54= 2*3.142*r
7.54=6.284*r
divide both sides by 6.284 we have
r= 7.54/6.284
r= 1.199
diameter = 2*r
diameter= 1.199*2
diameter= 2.399
to the nearest tenth
diameter= 2.40mm
