You’re correct answer is going to be your last option and how to get the answers 8×6 = 48 I tried all the other ones but that was the wrong answer so direct answer is your last option
S = πr(r + √(h² + r²))
400.2 = 3.14(6)(6 + √(h² + 6²))
400.2 = 18.84(6 + √(h² + 36))
18.84 18.84
21¹⁰⁹/₄₇₁ = 6 + √(h² + 36))
- 6 - 6
15¹⁰⁹/₄₇₁ = √(h² + 36)
231²²¹⁰⁰⁵/₂₂₁₈₄₁ = h² + 36
- 36 - 36
195²²¹⁰⁰⁵/₂₂₁₈₄₁ = h²
14 ≈ h
Answer:
Step-by-step explanation:
Newton's cooling model is:
Where
t is the time in hours
is the ambient temperature
is the initial temperature of the body
We know that:
Then after 7 hours the temperature of the liquid will be:
