Answer: I will answer.
Step-by-step explanation:
Given - radius of first field = 7m
Radius of second field = 25m
Area of first field = 22/7 * (7)^2
= 22/7 * 49
= 22* 7
= 154m^2
Area of second field = 22/7 * (25)^2
= 22/7 * 625
= 22 * 89.28
= 1964.16m^2
Difference =First - second
= 1964.16 - 154
= 1810.16
Area of third field = 22/7 * (r) ^2
= 1810.16 = 22/7 * (r) ^2
(r) ^2 = 22/7 * 42.54
(r) ^2 = 22* 6.07
(r) ^2 = 133.54
