To find the length of the wire that is bent to form four semi-circles, we need to know the radius of each semi-circle. Could you please provide the radius of the semi-circles?
To determine the length of the wire bent into four semicircles, we'll need to know the radius of the semicircles. Let's assume the radius is denoted by 'r'.
The formula to calculate the circumference (length) of a circle is given by:
C = 2πr
Since we have four semicircles, the total length of the wire can be obtained by multiplying the circumference of one semicircle by 4.
The formula to calculate the circumference of a semicircle is:
C_semicircle = πr + 2r
Substituting this value into the total length equation:
Total Length = 4 * (πr + 2r)
Simplifying the equation, we get:
Total Length = 4πr + 8r
Therefore, the length of the wire can be expressed as 4πr + 8r.
