The formula for finding the area of a circle can be written in many ways. If the radius is given, the formula is A=πr², where A=area, π=22/7 or 3.14, and r is the radius.
If the diameter is given, then the formula is A=1/4πd², where A is the area, π is 22/7 or 3.14 and d is the diameter
Given that the diameter is 46 inches and π=22/7 or approximately 3.14, the formula we can use is A=1/4πd² where A=area, π is 22/7 and d is 46
A=1/4*22/7*46*46
A=16662.57 inches² (It is rounded to nearest hundredth)
Answer:
AC = 6√3 in
Step-by-step explanation:
<h3>Finding the length of the chord:</h3>
Join OC. Now ΔAOC is an isosceles triangle as OA = OC =radius.
∠A = ∠C = 30.
∠A + ∠C + ∠AOC = 180 {angle sum property of traingle}
30 + 30 + ∠AOC = 180°
∠AOC = 180 -60
∠AOC = Ф = 120°
Find the length of radius using the bellow formula.
Ф = 120°
Arc length = 4π

<span>(m – 6)(m + 6) is the answer.
If you distribute them, you'll get </span><span>m^2 - 36</span>
Answer:
H.A.=4
Step-by-step explanation:
If the bottom equation is factored, you get (x+1)(x-4)
If the V.A. is -1 ( gotten by putting [x+1] equal to zero I'm guessing) then the H.A. can be gotten by putting (x-4) equal to zero.
Also, I graphed it.
