Jawab:
10 cm
Penjelasan dengan langkah-langkah:
V =1/3 πr²t
2198 = 1/3 .3,14. r². 21
2198 = 7 . 3,14.r²
2198 = 21,98r²
r² =2198/21,98
r²=100
r = √100
r =10
panjang jari jari kerucut adalah 10 cm

V = 2.198 CM
T = 21 CN
DIT = .....JARI JARI ?
PENYELESAIAN =
=> VOLUME = 1/3 × PHI × R^2 × T
=> 2.198 CM = 1/3 × phi x r^2 x 21 cm
=> 2.198 x 3 = 6.594 cm
=> 6.594 cm ÷ 21 cm
=> 314 ÷ 3,14
r^2 => 100 cm
r => 10 cm
