Question

The area of a circular field is 154msqu. What is the perimeter of the field?(pi=22/7) 44 49 88 176

Answer 1

Answer:

44m

Step-by-step explanation:

Area of circular field=154m²

Perimeter of the field=?

At first,

Area =22/7×r²

154m²= 22/7×r²

154×7/22=r²

49=r²

7×7=r²

7=r

Now,

Perimeter = 2×22/7×7

= 44m

Answer 2

Answer:

44m

Step-by-step explanation:

A = $\pi$r² = 154

   = 22/7 * r² = 154

   = r²  = 154 * 7/22

   = r²  = 49

   = r = √49

   = r = 7m

Perimeter of circle = 2$\pi$r

                               = 2 * 22/7 * 7

                               = 44/7 * 7

                               = 44 m
