no. 2
3/4 × Π × r^2
= 3/4 × 22/7 × 14^2
= 3/4 × 22/7 × 196
= 462

no. 3
Luas bangun trapesium - Luas bangun persegi
= ( 1/2 × ( a + b) × t) - ( s × s)
= ( 1/2 × ( ( 16 + 6 ) + 26 ) × ( 5 + 16 ) - ( 16 × 16 )
= ( 1/2 × ( 22 + 26) × 21 ) - 256
= ( 1/2 × 48 × 21 ) - 256
= ( 24 × 21 ) - 256
= 504 - 256
= 248

no. 4
sisi miring
= √8^2 + 6^2
= √ 64 + 36
= √100
= 10
KELILING
= 8 + 6 + 10
= 24
