Answer:
401.92 in²
Step-by-step explanation:
S.A. = 2πr²+2πrh
S.A. = 2π4²+2π4·12
S.A. = 100.48 + 301.44
S.A. = 401.92 in²

Answer:
D
Step-by-step explanation:
the value of the given expression when a = 2 is
2(2 + 6) = 2 × 8 = 16
calculating the values of the expressions when a = 2
A (2 × 2 ) + 2² = 4 + 4 = 8 ← less than 16
B (4 × 2) + 8 = 8 + 8 = 16 ← not greater than 16
C (2 × 2) + 12 = 4 + 12 = 16 ← not greater than 16
D + 2 = 16 + 2 = 18 ← greater than 16
