Answer:
sqrt(5)/29
Step-by-step explanation:
1/(5 + 3sqrt(5))
= 1/(5 + 3sqrt(5)) x sqrt(5)/sqrt(5)
= sqrt(5)/(5 + 3 x 8)
= sqrt(5)/ 29
Answer: $4.45
Step-by-step explanation: you will get $4.45
The circle has radius 6 feet, so its total circumference is 2<em>π</em> • (6 ft) = 12<em>π</em> ft.
As an arc, the complete circle corresponds to a central angle of 2<em>π</em> radians. So the red arc corresponds to a central angle <em>θ</em> such that
<em>θ</em> / (15 ft) = (2<em>π</em> rad) / (12<em>π</em> ft)
Then
<em>θ</em> = (15 ft) • (2<em>π</em> rad) / (12<em>π</em> ft) = 15/6 rad = 2.5 rad
