Answer:

Step-by-step explanation:

first lets find the circumference of the wheel:

[tex]C=\pi *d[/tex]

we have to find the diameter out of the radius:

[tex]d=r*2[/tex]

because the radius is half of the diameter, intrhis case i have to findf the diameter so i do multiply it with 2:

[tex]r=11\\d=??\\d=11*2\\d=22[/tex]

we found the diameter now we are going to find the circumference :

[tex]C=\pi *d\\C=\ 3.14*22\\C= 69.08[/tex]

Another way (easier)to find the circumference is:

[tex]C=2\pi *r\\C=2(3.14)*11\\C=69.08[/tex]

At the end it will hav ethe same answer.

Answer:

69.08 inches

Step-by-step explanation:

substitute the values of r (11 inches) and pi (3.14) in the formula c = 2πr to find c:

c =  2 × 3.14 × 11 inches

c = 69.08 inches.

the circumference of the wheel is about 69.08 inches.
