Answer:
Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715
Answer:
124.3 ft
Step-by-step explanation:
We solve the above question using the Trigonometric function of Tangent
= tan θ = Opposite/Adjacent
θ = Angle of Elevation = 73°
Adjacent = 38 ft
Opposite = x
Hence
tan 73° = x/38 ft
Cross Multiply
x = tan 73° × 38 ft
x = 124.2923995 ft
Approximately = 124.3 ft
Therefore, Nick is 124.3 ft from the ground.
Multiplying simultaneously numerator by numerator and denominator by denominator.
You can multiply fractions, multiplying simultaneously numerator by numerator and denominator by denominator.
2) Notice that whenever possible, we must simplify it to the lowest possible fraction.
