Answer:
154π cm²
Step-by-step explanation:
Radius (r) = 7 cm
Height (h) = 4 cm
Surface area of cylinder
= 2πr (h + r)
= 2π (7) (4 + 7)
= 2π (7) (11)
= 2π (77)
= 154π cm²

Answer:
<u>154π cm²</u>
Step-by-step explanation:
<u>Formula for the Surface Area of a Cylinder</u>
<u>Solving</u>
- Here r = 7 cm and h = 4 cm
- SA = 2πr (h + r)
- SA = 2π × 7 (7 + 4)
- SA = 14π × 11
- SA = <u>154π cm²</u>

Answer:
70 and 110
Step-by-step explanation:
First angle -- 2x
Second angle -- 3x + 5
Therefore,
2x + 3x + 5 = 180
5x = 175
x = 35
Therefore, 2x -- 70
3x + 5 -------------110
