Answer: 50.2656

Explanation:

  • Identify the formula to find the surface area of a circle.

Formula: πr² or π × r × r

  • Identify the values needed to calculate for the surface area.

π (pi) = 3.1416

r (radius) = 4 (divide the diameter by 2 in order to get the radius)

  • Calculate.

= π × r × r

= 3.1416 × 4 × 4

= 3.1416 × 16

= 50.2656
