Diameter = 42, Height = 10
Radius (r) = 42/2 = 21
Curved Area of Cylinder = 2πrh = 2 × (22/7) × 21 × 10
= 1320 sq cm
Total Surface Area = 2πrh + 2πr²
= 1320 + [2 × (22/7) × 21²]
= 1320 + 2772
=4092 sq cm

Answer:
Right cylinder
solve for surface area
A ≈ 4090. 35cm²
If diameter = 42cm
height = 10cm
