Find the ratio of the circumference of a circle with radius 1.125 to the circumference of a circle with diameter 2.25. express your answer in the form a: b where a and b are relatively prime positive integers.

Step-by-step explanation:

Circumference of a circle = πD, where D is the diameter.

Diameter of circle 1 = 1.125

Circumference of circle 1 = π x 1.125

Diameter of circle 1 = 2.25

Circumference of circle 1 = π x 2.25

Circumference of circle 1 : Circumference of circle 2 = 1 : 2

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°
