(a) 70 m
(b) 35 m
(C)65 m
(d)75 m
​

Answer 1

Answer:

since area of the circle pier^2

Pier^2=3850

22/7r^2=3850

r^2=3850×7/22

r=35

Answer(b)

Answer 2

Step-by-step explanation:

area of circle = πr²

3850 = 22/7 r²

3850*7/22 = r²

1225 = r²

35 ² = r ²

r = 35 m

so.radius is 35 then diamter = 2r

2*35 = 70 m
