$if ~radius=r \\volume =\frac{4}{3} \pi r^3\\113.1=\frac{4}{3} \pi r^3\\113.1 \times \frac{3}{4 \pi } =r^3\\\frac{339.3 }{4 \times 3.14} =r^3\\r^3=\frac{339.3}{12.56} \approx 27\\r=3\\area =\pi r^2=\pi *3^2=9\pi =9*3.14=28.26 \approx 28.3 ~m^2$

How to convert 6.9 to a fraction or mixed number

Marianna [84]

6.9 has 1 decimal, therefore we'll use 1 zero and lose the dot

$\bf 6.\underline{9}\implies \cfrac{69}{1\underline{0}}
\\\\\\
\textit{now, 10 goes into 69 \underline{6 times} with a \underline{remainder} of 9}\implies 6\frac{9}{10}$
