Answer:
Radius of the Earth is 3978.8 Miles
Circumference of the Earth is 25000 Miles
Step-by-step explanation:
The angle of the sun shone at an angle of 7.2° to the zenith
This means that the angle of the sector of the circle is 7.2° (θ)
S = Length of the sector of the circle = 500 miles
r = radius of earth
Converting 7.2° to radians


∴ Radius of the Earth is 3978.8 Miles

∴ Circumference of the Earth is 25000 Miles

Triangle 2: 20.91
Step-by-step explanation:
Square area formula: area=
Triangle: area=
Answer:
domain: x ≥ -5
range: y ≥ 0
Step-by-step explanation:
notice the equation contains √x + 5
since anything inside a square root must not be negative, the domain is restricted to x + 5 ≥ 0 so solving for x, we have:
x ≥ -5 as the domain.
by inspecting the graph, the range is:
y ≥ 0
