Di jawab ya pakai cara Soal tentang volume bangun ruang sisi lengkung

Tinggi kerucut

[tex] \sqrt{25 {}^{2} - 7 {}^{2} } \\ \\ = \sqrt{625 - 49} \\ \\ = \sqrt{576} \\ \\ = 24 \: cm[/tex]
Volume gabungan

= ( π × r × r × t ) + ( 1/3 × π × r × r × t )

= ( 22/7 × 7 × 7 × 20 ) + ( 1/3 × 22/7 × 7 × 7 × 24 )

= 3.080 cm3 + 1.232 cm3

= 4.312 cm3

Option = C
