(sisi alas kerucut)² = (sisi miring kerucut)² - (tinggi kerucut)²

= 26² - 24²

= 676 - 576

= 100

sisi alas kerucut = √100

= 10 cm

V.½ bola = 4/3 × 1/2 × π × r²

= 4/6 × 3,14 × 10 × 10

= 209,3 cm³

L.½ bola = 1/2 × 4 × π × r²

= 2 × 3,14 × 10 × 10

= 2 × 314

= 628 cm²

V. tabung = π × r² × t

= 3,14 × 10 × 10 × 50

= 15.700 cm³

L. tabung = π × r²

= 3,14 × 10 × 10

= 314 cm²

V.kerucut = 1/3 × π × r² × t

= 1/3 × 3,14 × 10 × 10 × 24

= 314/3

= 2.512 cm³

L. kerucut = π × r (r + s)

= 3,14 × 10 (10 + 26)

= 3,14 × 10 × 36

= 3,14 × 360

= 1.130,4 cm²

Total volume = V.½ bola + V. tabung + V. kerucut

= 209,3 + 15.700 + 2.512

= 18.421,3 cm³

Total Luas = L.½ bola + L. tabung + L. kerucut

= 628 + 314 + 1.130,4

= 2.072,4 cm²
