The radius of the penny is 9.54 millimeters.
The circumference means the length of the literal line that surrounds and forms a circle.
The formula for the circumference of the circle is given by
r is the radius
and π = 3.14
A radius is a straight line from the center of a circle to the circumference of a circle.
According to the given question.
We have a penny whose circumference is 59.69 millimeters.
Let r be the radius of the penny and 2πr be the circumference of the penny.
Since we know that, the shape of the penny is circular.
The radius, r of the penny is given by
Hence, the radius of the penny is 9.54 millimeters.

The circumference of the circle is given as 2r where is a constant whose value is equal to 22/7 and r is the radius of the circle
From the given problem, we have the circumference =37.7
2r = 37.7
2*22/7*r = 37.7
r = 37.7*7/(22*2)
r = 263.9/44
r = 5.99
r = 6cm
Radius = 6 centimeters (Rounded to nearest whole number)
