A circular path 4 feet wide has an inner diameter of 550 feet. How much farther is it around the outer edge of the path than aro

Softa [21]

Answer:

$L_c=25.12ft$

Step-by-step explanation:

From the question we are told that

Width of circular path $w_c=4ft$

Inner Diameter $d_i_n=550ft$

Outer diameter $d_{out}= 550 +2*4$ (inner diameter + 2 circular path width)

$d_{out}= 550 +8\\d_{out}= 558ft$

Generally the equation for inner circumference of the circle $C_1$ is mathematically given by

$C_1=\pi d_{in}$

$C_1=3.14*550$

$C_1=1727ft$

Generally the equation for outer circumference of the circle $C_2$ is mathematically given by

$C_2=\pi d_{out}$

$C_2=3.14*558$

$C_2=1752.12ft$

Generally the difference in length of the two circumference $L_c$ is mathematically given by

$L_c=C_2-C_1$

$L_c=1752.12-1727$

$L_c=25.12ft$
