Answer:
A=2πrh+2πr2
A=2πrh+2πr2Solving forr
A=2πrh+2πr2Solving forrr=1
A=2πrh+2πr2Solving forrr=12h2+2A
A=2πrh+2πr2Solving forrr=12h2+2Aπ﹣h
A=2πrh+2πr2Solving forrr=12h2+2Aπ﹣h2=1
A=2πrh+2πr2Solving forrr=12h2+2Aπ﹣h2=12·632+2·1980
A=2πrh+2πr2Solving forrr=12h2+2Aπ﹣h2=12·632+2·1980π﹣63
A=2πrh+2πr2Solving forrr=12h2+2Aπ﹣h2=12·632+2·1980π﹣632≈4.65767cm
