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