Kunci Jawaban Matematika Kelas 9 Halaman 293 294 295 296 Latihan 5 2 Kerucut, Semester 2: Lengkap Nomor 1 - 10

c. s = √(r² + t²)
s = √(6² + 10²)
s = √(36 + 100)
s = √136 = 2√34

Lp = πr(r + s)
Lp = 3,14 x 6(6 + 2√34)
Lp = 18,84(17,66)
Lp = 332,75 cm²

V = ⅓ πr²t
V = ⅓ x 3,14 x 6² x 10
V = 376,8 cm³

d. t = √(s² - r²)
t = √(25² - 7²)
t = √(625 - 49)
t = √576 = 24

Lp = πr(r + s)
Lp = 22/7 x 7(7 + 25)
Lp = 22(32)
Lp = 704 cm²

V = ⅓ πr²t
V = ⅓ x 22/7 x 7² x 24
V = 1232 cm³

e. r = √(s² - t²)
r = √(4² - 3²)
r = √(16 - 9)
r = √7
