The formula for area in terms of radius is
... A = πr²
Solving this for r, we get
... A/π = r²
... r = √(A/π) . . . . . formula for the radius
For your given area, the radius is approximately
... r = √(401.92/3.14) = √128 = 8√2
... r ≈ 11.3 . . . yards
What is your question? Are you asking if her equation is correct?
Answer:
b 15 - 4i sqrt(2)
Step-by-step explanation:
15 - sqrt (-32)
15 - sqrt(-1) sqrt(32)
15 - ±i sqrt(16) sqrt(2)
15 - ±4i sqrt(2)
Taking the principal square root
15 - 4i sqrt( 2)
The lengths of the bases would be 3 and 9
