Jawaban:
Diketahui:
r = 7 cm
t = 10 cm
Ditanya:
A. Luas tabung
B. Luas Permukaan tabung
C. Volume tabung
Jawab:
Luas tabung sama dengan Luas Permukaan tabung.
L = (2×π×r²) + (2×π×r×t)
L = (2×22/7×7²) + (2×22/7×7×10)
L = (2×22×7) + (2×22×10)
L = 308 + 440
L = 748 cm²
Luas Permukaan tabung sama dengan Luas Tabung.
LP = (2×π×r²) + (2×π×r×t)
LP = (2×22/7×7²) + (2×22/7×7×10)
LP = (2×22×7) + (2×22×10)
LP = 308 + 440
LP = 748 cm²
V = π × r² × t
V = 22/7 × 7² × 10
V = 22 × 7 × 10
V = 1.540 cm³
SEMOGA MEMBANTU

Langkah penyelesaian:
Diketahui:
r = 7 cm
t = 10 cm
Ditanya:
A. Luas tabung
B. Luas Permukaan tabung
C. Volume tabung
Jawab:
A. Luas tabung
Luas tabung sama dengan Luas Permukaan tabung.
L = (2×π×r²) + (2×π×r×t)
L = (2×22/7×7²) + (2×22/7×7×10)
L = (2×22×7) + (2×22×10)
L = 308 + 440
L = 748 cm²
B. Luas Permukaan Tabung
Luas Permukaan tabung sama dengan Luas Tabung.
LP = (2×π×r²) + (2×π×r×t)
LP = (2×22/7×7²) + (2×22/7×7×10)
LP = (2×22×7) + (2×22×10)
LP = 308 + 440
LP = 748 cm²
C. Volume Tabung
V = π × r² × t
V = 22/7 × 7² × 10
V = 22 × 7 × 10
V = 1.540 cm³
