Answer:
Step-by-step explanation:
From the question we are told that
Width of circular path
Inner Diameter
Outer diameter (inner diameter + 2 circular path width)
Generally the equation for inner circumference of the circle is mathematically given by
Generally the equation for outer circumference of the circle is mathematically given by
Generally the difference in length of the two circumference is mathematically given by
9514 1404 393
Answer:
2.8¢, true
Step-by-step explanation:
The value of copper in a penny is reportedly about ...
(0.95 × 3.11 g)×(1 oz)/(28.35 g)×($0.27/oz) ≈ $0.028
Today, the value of the copper in a pre-1982 penny is about 2.8¢, more than double the value of the penny as legal tender.
The claim is true.
The equation of circle in standard form is
Given that circle having center point (3,7) and the radius r = 4
To find: equation of circle in standard form
<em><u>The equation of circle is given as:</u></em>
Where center (h,k) and radius r units
Given that center point (h , k) = (3, 7) and radius r = 4 units
Substituting the values in above equation of circle,
Thus the equation of circle in standard form is
