(22/7 × 0,7 ×0,7) + (2 × 22/7 × 0,7 × 5)
1,54 + 22 = 23,54 cm
πrs=luas pemukaan kerucut tanpa alas
mencari s = t² + a²
s = 5² + 0.7²
=25 +0,49
= 5,05 cm
lk = 22/7 × 0.7 × 5,05
= 11.09
lp.tabung +lp.kerucut
23,54 +11.09 = 34,6 cm
= 22/7 x 0,7 x 0,7
= 1.54
L2 = 2 x Π x r x t
= 2 x 22/7 x 0,7 x 5
= 22
L3 = Π x r x s
= 22/7 x 0,7 x 2.5
= 5,5
L = 1,54 + 22 + 5,5
= 29,04
