We have the following equation:
x2 + 4x = - (y2 - 20)
Let's review step by step:
step 1:
x2 + 4x = -y2 + 20
Answer: OK
step 2:
x2 + 4x + 4 = -y2 + 20 - 4
Answer: Wrong
The correct step is:
x2 + 4x - 4 = -y2 + 20 - 4
Or equivalently:
x2 + 4x + 4 = -y2 + 20 + 4
Answer:
he did make an error in his work in step 2
I think your answer would be $69984. But I'm not 100 percent.
Surface area = 4πr²
⇒ 400 = 4 * 3.14 * r²
⇒ r² = 400/12.56
⇒ r² = 31.84
⇒ r = √31.84 = 5.64 inches
Answer is A.
