Answer:

1,200 +3(60)

Step-by-step explanation:

1200 is where they started so every three hour period the submarine rises 60 ft per hour. So you multiply it by this and then 60. Positive because you are rising, and not going down.

Please can someone answer this for the love of GOD?! Please and I will give you 5 stars or a Thanks?!
FrozenT [24]

Answer:

4) 120π cm^2

5) 56π cm^2

6) 32π cm^2

Step-by-step explanation:

Surface Area of Cylinder = 2πr^{2} + (2πr)(height)

(will use variable h for height)

4)

diameter = 8 cm

r = 0.5(diameter) = 0.5(8) = 4 cm

height = 11 cm

2π4^{2} + (2π)(4)(11)

= 2π(16) + 2π(44)

= 32π + 88π

= 120π cm^2

5)

diameter = 8 cm

r = 0.5(diameter) = 0.5(8) = 4 cm

height = 6 cm

2π4^{2} + (2π)(4)(6)

= 2π(16) + 2π(12)

= 32π + 24π

= 56π cm^2

6)

diameter = 6 cm

r = 0.5(diameter) = 0.5(6) = 3 cm

height = 7 cm

2π3^{2} + (2π)(3)(7)

= 2π(9) + 2π(7)

= 18π + 14π

= 32π cm^2
