Answer:
A = πr² ← r is the radius and r = \frac{1}{2} d ← d is the diameter
Hence
π (\frac{1}{2} d)² = A, that is
\frac{d^2\pi }{4} = A ( multiply both sides by 4 )
d²π = 4A ( divide both sides by π )
d² = \frac{4A}{\pi } ( take the square root of both sides )
d = \sqrt{\frac{4A}{\pi } }

Answer:
2.2084384 in cents, and 22.084384 in dollars
Step-by-step explanation:
Apologies in advance if I've got something wrong, it's currently 12:08 at night for me njnhrj
First we'd like to figure out how much we have after calculating the weight left over after charging for the first ounce.
7.90137-1=6.90137
Multiply by .32, and you've got your sum in cents; 2.2084384
Divide this by 0.1 and you've got it in dollars; 22.084384
Answer:
37.69 (≈ 38 ft²)
Step-by-step explanation:
2πr = 30.77
r = 30.77 / (2 * 3.14) = 4.9
half of free-throw circle area: πr² / 2 = (3.14 * 4.9²) / 2 = 37.69 (≈ 38 ft²)
