10. Luas permukaan = 2πr(r + t) = 2 x 22/7 x 7(7 + 15) = 44(22) = 968 cm²
11. V = πr²t 314 dm² = 3,14 x 5 dm x 5 dm x t t = 4 dm = 40 cm
12. A
13. L = πr(r + s) = 3,14 x 6(6 + 10) = 301,44 cm²
14. cari t nya dulu t = √(17² - 8²) = 15 cm V = πr²t = 3,14 x 8 cm x 8 cm x 15 cm = 3014, 4 cm³
= 2 x 22/7 x 7(7 + 15)
= 44(22)
= 968 cm²
11. V = πr²t
314 dm² = 3,14 x 5 dm x 5 dm x t
t = 4 dm
= 40 cm
12. A
13. L = πr(r + s)
= 3,14 x 6(6 + 10)
= 301,44 cm²
14. cari t nya dulu
t = √(17² - 8²)
= 15 cm
V = πr²t
= 3,14 x 8 cm x 8 cm x 15 cm
= 3014, 4 cm³
