Question

Tolong bantu saya kak! hari ini dikumpulin

Answer 1

Sisi miring = √(70.70) + (105.105)
sisi miring = 126.2 cm
volume kerucut = 3.14 . 70 . (70+126.2)
volume = 219.8 x 196.2
volume = 43,124.76 cm3
volume = 43.12476 dm3 atau liter

Answer 2

Tumpeng = kerucut
v. kerucut = 1/3 πr²t
= 1/3 22/7 70 x 70 x 105
= 1/3 220 x 70 x 105
= 35 x 220 x 70
= 7.700 x 70
= 539.000 cm³
= 539 dm³
atau
539 liter
