Answer:

3.1 in

Step-by-step explanation:

In any circle the following ratios are equal

\frac{arc}{circumference} = \frac{angleatcentre}{2\pi }

\frac{4}{2r\pi } = \frac{\frac{5\pi }{12} }{2\pi }

\frac{4}{2r\pi } = \frac{5}{24} ( cross- multiply )

10πr = 96 ( divide both sides by 10π )

r = \frac{96}{10\pi } = 3.1 in ( nearest tenth )

Answer:

radius = arc length / central angle in radians

radius = 4 inches / 5*PI / 12

radius = 4 / 1.308996939 radians

radius = 3.0557749074

radius = 3.0557749074 inches

Find the sum of the first 6 terms in the sequence -5 -25 -125 -625
sashaice [31]
This is a geometric sequence, so use the formula for the sum of a geometric sequence:
Sum = (a(r^n - 1))/(r - 1)
where a is the first term, -5
r is the common ratio, 5
and n is the number of terms

Thus,
Sum = ((-5)(5^6 - 1))/(5-1) = -19530
