Jawaban:
a. 401,92 cm³
b. 1.232 cm³
c. 8038,4 cm³
Penjelasan dengan langkah-langkah:
a. V kerucut
= ⅓ x La x t
= ⅓ x ( π x r x r ) x t
t² = c² - a²
= 10² - 8²
= 100 - 64
= 36
t = √36
= 6 cm
= ⅓ x ( 3,14 x 8 x 8 ) x 6
= ( 3,14 x 8 x 8 ) x 2
= 200,96 x 2
= 401,92 cm³
b. V kerucut
= ⅓ x La x t
= ⅓ x ( π x r x r ) x t
= ⅓ x ( 22/7 x 7 x 7 ) x 24
= ( 22 x 7 ) x 8
= 154 x 8
= 1.232 cm³
c. V kerucut
= ⅓ x La x t
= ⅓ x ( π x r x r ) x t
r = d ÷ 2
= 32 ÷ 2
= 16 cm
= ⅓ x ( 3,14 x 16 x 16 ) x 30
= ( 3,14 x 16 x 16 ) x 10
= 803,84 x 10
= 8.038,4 cm³
Semoga dapat membantu
dan mohon maaf bila salah
