Find the circumference and the area of a circle with radius 7ft . Use the value 3.14 for pi, and do not round your answers. Be sure to include the correct units in your answers.

C=43.96 ft.

A=153.86 ft.^2

Step-by-step explanation:

for circumference, use C=2πr

for area, use A=π

C=43.96 ft

A=153.86 ft.^2

Step-by-step explanation:

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°
