What is the surface area of a sphere with a radius of 16 units?

option D

1024π units²

Step-by-step explanation:

Given in the question that radius of a sphere = 16 unit

Formula to use to calculate the surface area of the sphere

here r is the radius of the sphere

4 π (16)²

4 π (256)

1024π units²

Surface area of a sphere with radius 16 units = 1024π units²

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
