Объяснение:
Образующая конуса - гипотенуза в прямоугольном треугольнике
Высота и радиус основания - катеты
х cм - высота (h) , катет
(х-7) см - радиус (R) , катет
образующая=17см - гипотенуза
По теореме Пифагора:
х²+(х-7)²=17²
х²+х²-14х+49=289
2х²-14х-240=0
х²-7х-120=0
D=b²-4ac
D=49+480=529
х=(7+23):2
х=15(см) - h, высота конуса
15-7=8(см) - R основания
V = ⅓πR²h
V = ⅓*15*3,14*8² = 1004,8(см³)
