Find the circumference of the circle in terms of pi. a. 39 in b. 1521 in. c. 78 in d. 156 in

The circumference of the circle with radius is given by . When ,

Correct choice is (C).

Option C is correct

78 π inches

Step-by-step explanation:

Circumference (C) of a circle is given by:

                  .....[1]

where, r is the radius of the circle.

As per the statement:

From the given figure;

radius of the circle(r) = 39 in.

Substitute this value in [1] we have;

Therefore, the value of circumference of the circle in terms of pi is,

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
