Answer:
D. 8
Step-by-step explanation:
2p=16
divide both sides by 2 to get p alone
p=8
The formula for circumference is C = 2πr.
The question gives you the circumference (C in the formula), and you need to find the radius (r in the formula). Begin by isolating r in the circumference formula.
C = 2πr
C/2π = r
r = C/2π
Now you can plug 96 for C and solve to find r.
r = C/2π
r = 96/2π
r ≈ 96/6.28
r ≈ 15.29
Answer:
The radius of a circle with a circumference of 96 feet is approximately 15.29 feet.

Answer:
The Distance Formula itself is actually derived from the Pythagorean Theorem which is a 2 + b 2 = c 2 {a^2} + {b^2} = {c^2} a2+b2=c2 where c is the longest side of a right triangle (also known as the hypotenuse) and a and b are the other shorter sides (known as the legs of a right triangle).
