A. V. Kerucut : V. Tabung 1/3 πr²t : 1πr².t 1/3 π.6².8 : π.6².8 1/3 π.36.8 : π.36.8 1/3 288π : 288π 1/3 : 1 1 : 3
b. L, selimut tabung = K. lingkaran x t = πd x t = 3,14 x 12 x 8 = 301,44 cm²
c. L. selimut kerucut = π.r.s = 3,14 x 6 x √6²+8² = 18,84 x √36+64 = 18,84 x √100 = 18,84 x 10 = 188,4 cm²
1/3 πr²t : 1πr².t
1/3 π.6².8 : π.6².8
1/3 π.36.8 : π.36.8
1/3 288π : 288π
1/3 : 1
1 : 3
b. L, selimut tabung = K. lingkaran x t
= πd x t
= 3,14 x 12 x 8
= 301,44 cm²
c. L. selimut kerucut = π.r.s
= 3,14 x 6 x √6²+8²
= 18,84 x √36+64
= 18,84 x √100
= 18,84 x 10
= 188,4 cm²
t=8cm
s=√6² + 8²
=√36 + 64
=100
=√100
= 10
a) Vtabung : Vkerucut
La x t : la × t
πr²t : πr²t
3.14 × 6 × 6 × 8 : × 3.14 × 6 × 6 × 8
904.32 : 301.44
3 : 1
b) 2πrt = 2 × 3.14 × 6 × 8
= 301.44
c) πrs= 3.14 × 6 × 10
= 188.4
