tinggi kerucut = V(s^2 - r^2) = V(30^2 - 7^2) = V(900 - 49) = V851 cm = 29,17 cm

Diketahui : ↓ Rumus tinggi kerucut = V(s² - r²) r ( Jari - jari ) = 7 cm s ( Garis pelukis ) = 30 cm Tinggi kerucut : ↓ t = V(s² - r²) t = V(30² - 7²) t = V(900 - 49) t = V851 cm t = 29,17 cm
r = 7 cm
s = 30 cm
tinggi kerucut = V(s^2 - r^2)
= V(30^2 - 7^2)
= V(900 - 49)
= V851 cm
= 29,17 cm
Rumus tinggi kerucut = V(s² - r²)
r ( Jari - jari ) = 7 cm
s ( Garis pelukis ) = 30 cm
Tinggi kerucut : ↓
t = V(s² - r²)
t = V(30² - 7²)
t = V(900 - 49)
t = V851 cm
t = 29,17 cm
