wood, wood glue, bolts, steel wire
106" x 106" x 4"
and r sub two equals thirteen. Diameter equals height equals width. Diameter equals two r equals two times fifty-three. Diameter equals one hundred and six. Height equals one hundred and six. Width equals one hundred and six. Circumference equals two pi r. Circumference equals two pi times fifty-three. Pi is about equal to three point one four. Circumference equals three hundred thirty-two and eighty-four hundredths. Area equals pi r squared. Area equals pi r sub one squared minus pi r sub two squared. Area equals pi times the quantity fifty-three squared minus thirteen squared. Area equals two thousand six hundred forty pi. Pi rounded to the nearest hundredth equals three and fourteen hundredths. Area equals eight thousand two hundred eighty-nine and six tenths.
