Answer 1

Answer:

radius = 24.5 m

circumference = 1886.5 sq.m

Step-by-step explanation:

π = 22/7

2*π*r = Circumference

2*22/7*r = 154

22/7*r = 22/7*r = 154/2

22*r = 77*7

22r = 539

r = 539/22

r = 49/2 m

r = 24.5 m

Area of Circle = 22/7*r^2 = 22/7*(49/2)(49/2) = 2401/4 * 22/7 = (343*11)/2 = 3773/2

= 1886.5 sq.m
