Question

area of circle is 49 pi sq mts then its perimeter is​

Answer 1

ANSWER:--------

given area of the circle = 49m²

formula to find the area of a circle is πr²

therefore πr² = 49m²

→ 22/7 × r² = 49m²

→ r² = 49 × 7/22

→ r² = 343/22

→ r² = 15.5 (approximately)

→ r = √15.5

→ r = 3.9cm (approximately)

hence, it's circumference = 2πr

= 2 × 22/7 × 3.9

= 171.6/7

= 24.5cm (approx)

Answer 2

Answer: Perimeter: 44m

Step-by-step explanation:

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.

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