Question

The area of a circle 49 π. Then the radius of circle

Answer 1

Answer:

Area of the circle is given as 49 pi sq m

Formula for finding out the area of a circle is:

Area= pi r2 , where r - radius of the circle.

Here, pi r2= 49 pi

So, r2 = 49 ; r= 7m

Formula for finding out the perimeter or circumference of a circle:

Perimeter= 2 pi r

= 2 pi × 7 m

= 14 pi m

Putting the value of pi as 22/7:

Perimeter= 14× 22/7 m = 44m.

So, the perimeter of the given circle can be noted as 44m.

Answer 2

Answer:

the radius is 7

Step-by-step explanation:

49=πr^2

r^2=49

r=7
