Maaf kalau salah :)

1. V = R × R × R

= 15 × 15 × 15

= 3.375 cm^3 (c)

2. V = La × T

= (1/2 × a × t) × T

= (1/2 × 8 × 7) × 16

= (1 × 4 × 7) × 16

= 28 × 16

= 448 cm^3 (b)

4. V = phi × r^2 × t

9.900 = 22/7 × r^2 × 14

9.900 = 22 × r^2 × 2

9.900 = 44 × r^2

r^2 = 9.900 ÷ 44

r^2 = 225 (diakarkan pangkat 2)

r^2 = 15^2 (A)
