Answer:
Surface Area: 1008π OR 3166.73
Volume: 4320π OR 13,571.68
Step-by-step explanation:
Surface Area Equation:
2πrh+2πr^2
Work:
2π (12) (30) + 2π12^2
2π(360) + 2π(144)
720π + 288π
1008π OR 3166.73
Volume Equation:
πr^2h
Work:
π12^2 (30)
π144 (30)
4320π OR 13,571.68

Answer:
4/2
Step-by-step explanation:
Question 7= to work out 19% work out 1% and 20%. 25.00 1%= 0.25 10%= 2.5 so, 20% = 5 (2.5*2) 20%-1% = 19%. 5-0.25 = 4.75 = discount £25-£4.75 =20.25
