Answer:3600units
Step-by-step explanation:
Circumference=11304
π=3.14
Circumference=π x diameter
11304=3.14 x diameter
Dividing both sides by 3.14 we get
diameter=11304 ➗ 3.14
diameter=3600
3f + 2g = 30 . . .(1)
f + 2g = 26 . . . .(2)
(1) - (2) => 2f = 4 => f = 4/2 = 2
From (2), 2 + 2g = 26 => 2g = 26 - 2 = 24 => g = 24/2 = 12
Therefore, f = 2 and g = 12
Mid section: 15 * 7 = 105
left triangle: 1/2 * 4 * 7 = 14
right triangle: 1/2 * 6 *7 = 21
total: 105 + 14 + 21 = 140 in^2
