a. 900[tex]\pi[/tex] in.
b. 90[tex]\pi[/tex] in.
c. 60[tex]\pi[/tex] in.
d. 30[tex]\pi[/tex] in.

Answer:

[tex]c. \: 60\pi \: in.[/tex]

Step-by-step explanation:

Given,

Radius = 30 in

So,

Circumference

[tex] = 2\pi r[/tex]

[tex] = 2 \times \pi \times 30in.[/tex]

[tex] = 60\pi \: in.(ans)[/tex]

[tex] \sf \: r \: = 30 \: in. \\ \sf \: C \: = 2\pi r \\ \\ \sf \: C \: = 2\pi(30) \\ \sf \: C = 2 \times 30\pi \\ \sf \: C = \boxed{\underline{ \bf c. \: 60\pi \: in.}}[/tex]
