Question

Find the circumference of the circle with the radius 49cm. Use 22/7 for pi. Pls help :)

Answer 1

Answer:  308 cm

Work Shown:

C = 2*pi*r

C = 2*(22/7)*49

C = 2*22*(49/7)

C = 2*22*7

C = 308

The circumference of the circle is the same as the perimeter around the circle's outer edge. It's approximately 308 cm. The value is approximate because pi = 22/7 is approximate.
