A)
30 ÷ 100 = 0.3 x 15 = 4.5 (This statement is false)
B)
80 ÷ 100 = 0.8 x 25 = 20 (This statement is true)
C)
50 ÷ 100 = 0.5 x 30 = 15 (This statment is false)
D)
60 ÷ 100 = 0.6 x 30 = 18 (This statement is true)
E)
20 ÷ 100 = 0.2 x 40 = 8 (This statement is true)

The area of the circle is 113.1 sq ft
To find the circumference of the circle we need to find the radius of the circle first
Formula
The area of circle with radius r is = π sq unit
The circumference of circle with radius r is = 2πr unit
Let us take the radius of the circle is r ft
According to the problem,
π
or,
or,
or, r =
or, r = 6
Now,
The circumference of the circle is 2×3.14×6 ft = 37.68 ft
