Answer:
(Round your answer up to the nearest whole number.)(b) Repeat part (a) using a 99% confidence level. (Round your answer up to the nearest whole number.)
Step-by-step explanation:
V=<span><span>π <span>r^2</span></span><span>h/<span>3
V = </span></span></span>π r 5^2 16/3
Raise 5<span> to the </span>power<span> of </span>2<span> to get </span><span>25.
</span><span>V=π*25*<span>16/3
</span></span>Move 25<span> to the left of the </span>expression <span><span>π⋅25</span>.
</span><span>V=25*π*<span>16/3
</span></span>Multiply 25<span> by </span>π<span> to get </span><span><span>25π</span>.
</span><span>V=25π*<span>16/3
</span></span>
Multiply <span>25π</span><span> by </span><span>163</span><span> to get </span><span><span>25π(<span>16/3</span>)</span>.
</span><span>V=25π(<span>16/3</span>)</span>
Simplify
Multiply 16<span> by </span>25<span> to get </span><span>400.</span>
<span>V=(<span>400/3</span>)π</span><span>
</span>
Combine <span>400/3</span><span> and </span><span>π/1</span><span> to get </span><span><span><span>400π/</span>3</span>.
</span><span>
V=<span><span>400π/</span>3</span></span>
V≈<span>418.8790</span>
