Question

The area of a circle is 49π cm^2. Find the circumference of the circle.​

Answer 1

Answer:

Step-by-step explanation:

Area of a circle=29π cm^2

Area of a circle=πr^2

29π=πr^2

r^2=29

r=√29cm

Circumference=2πr

=2π×√29

=2√29π cm

Answer 2

Answer:

14 pie cm (or) 44 cm

Step-by-step explanation:

pie (r)^2=49pie

{pie on both sides get cancelled}

r^2=49

r=root (49)

r=7 cm

circumference ofthe circle= 2 pie r

= 2 *22/7*7[ seven gets cancelled]

= 44 cm (or) without substituting pie value

you get 14 pie
