Question

Jika tinggi kerucut 24 cm dan panjang garis pelukisnya 26. maka volume bangun tersebut adalah?

Answer 1

R^2 = s^2 - t^2
r^2 = 26^2 - 24^2
r^2 = 676 - 576
r = √100
r = 10 cm

V = 1/3.phi.r^2.t
V = 1/3.3,14.10^2.24
V = 2512 cm3

Answer 2

1/3×pi×r×r×t
1/3×3,14×26×26×24
26×26×26×24×3.14÷3
70,304

maaf ya kalau salah
