この問題の2ページ クケコサについての質問です。 3ページの色をつけてある部分がなぜ求められるのか分かりません。 t🟰0の時最小になるのは分かるのですが、なぜx🟰yの時も最小になるのでしょうか? また、12が出てくる理由もあまり分かってません。 解説お願いします!

2tx+2y +12=60匹 (i)太郎さんの方針でSの最小値について考察する。 288 数学Ⅰ 数学A 第2問 (配点 30) [1] 長さ60cmの針金を三つに分割し、 三つの円 Cx, Cy, Cz を作る。 Cx, Cy, Czの半径をそれぞれxcm, ycm, zcm とすると, 2πx+2y+2πz=60π が 成り立つ。ただし,xyz0 とする。 さらに, Cx, y, z の面積の和をS とすると,S=x2+y^+22)πが成り立つ。 BOT 2 24 であるから Cz Cy Cx (1) z=6 とする。 太郎さんと花子さんは, Sの最小値について考えている。 24 Tx+y=247 x+y=240 8.76 1152 y=アイ-x S ウ 144 2数学Ⅰ 数学A (パー(+36) X=121324 g=12. 272-484 8686210 である。 よって, Sの最小値は I である。 288 324 ウ の解答群 ⑩ x-48x + 576 144 ② 2x²-48x+576 288 +36 エ の解答群 ⑩ 288 ①324 ② 576 花子: z=6 のとき, S= (x2+y^ +36) πとなるね。 太郎: yはx を用いて表すことができるから, Sをxの関数として考えれ ばよさそうだね。 00 324 24 4 る 96 48 576 36 FEN²-98x+6(2) 6292 214-12)+324 + x2-48x +612 ③ 2x2-48x+612 612 (数学Ⅰ 数学A 第2問は次ページに続く。) (数学Ⅰ, 数学A第2問は次ページに続く。)
