Step-by-step explanation:
Exterior angle is the angle between any side of a shape, and a line extended from the next side.
65% = 65/100 = 0.65
30 * 0.65 = 19.5 acres are available for farming.

Step-by-step explanation:
A
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 12 , then radius = 12 ÷ 2 = 6 , then
A = π × 6² = 3.14 × 36 = 113.04 m²
B
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here C = 28.26 , then
2πr = 28.26 ( divide both sides by 2π )
r =
=
= 4.5 in
