a). Volume kerucut
V = 1/3 × π × r × r × t
= 1/3 × 22/7 × 7 × 7 × 24
= 1/3 × 154 × 24
= 1/3 × 3.696
= 1.232 cm²
b). panjang garis pelukis
s = √24² + 7²
= √576 + 49
= √625
= 26 cm
c). luas selimut
LS = ( π × r × s )
= 22/7 × 7 × 26
= 22 × 26
= 572 cm²
d). luas permukaan
LP = (π × r) (r + s)
= (22/7 × 7) (7 + 26)
= 22 × 33
= 726 cm²
