Answer:
sorry i cant answer that one man.
Step-by-step explanation:
[1], [3] => a = 49,000/2 = 24,500 => b +c = 24,500 => c = 24,500 - b;
[2] => 25*24,500 + 20b + 15c = 1,052,000 => 20b + 15c = 1,027,500;
20b + 15*(24,500 - b) = 1,027,500 => 5b = 733,500 => b = 146,700 =>
c = - 122,200;
Circumfrence: pi times diameter
7.9*

circumfrence is approximatley 24.806
area:

a=

*(1/2(d))^2
a= 48.99
