Question

area of circular field is 153.86 cm . find the radius and the circumfarence of the fiel​d

Answer 1

Answer: area = 153.86

Circumfrance = 2×22/7×r

153.86 = 2×22/7×r

R = 2/153.86×22/7

Answer 2

Answer:

r=6.9 & c=

Step-by-step explanation:

area of circle = $\pi$r^2

   153.86        = 22/7 * r^2

153.86*7/22   = r^2

       48.3         = r^2

        √48.3      =r

            r= 6.9

circumference of the circle= 2$\pi$r

                                             =2*22/7*6.9

                                              =303.6/7

                                              =43.3

Therefore, radius=6.9 and circumference=43.3
