The arc length is:
 S = R * theta
 Where,
 R: Radio
 Theta: central angle
 Substituting values we have:
 Circle A:
 Sa = Ra * (140/360) * 2π
 Circle B:
 Sb = Rb * (140/360) * 2π
 The relationship of arcs is:
 Sa / Sb = (Ra * (140/360) * 2π) / (Rb * (140/360) * 2π)
 Rewriting:
 Sa / Sb = (Ra / Rb)
 Substituting values:
 (3 / 4π) / Sb = 2/3
 Clearing Sb
 Sb = (3/2) (3 / 4π)
 Sb = (9 / 8π)
 Answer:
 
The length of the intercepted arc for circle B is:
 
Sb = (9 / 8π)

A rectangle with an area of 5/8 ft² is dilated by a factor of 8. What is the area of the dilated rectangle?
galben [10]
A dilation is basically a factor of enlargement or reduction, where you multiply the factor for the dilation. 

So,

Multiply the numerator 5 by the factor of 8. 

5*8= 40 

40/8 ft^2= 5 ft^2

The new area if 5 ft^2. 

I hope this helps!

The measures of the angles of a triangle are in the ratio 2:3:4. In degrees, the measure of the largest angle of the triangle is
notsponge [240]
Since the three angles of a triangle add to give 180°

The the size of the largest angle 4 = 180° × \frac{4}{2+3+4}
                                                       =  180° × \frac{4}{9}

∴ the size of the largest angle = 80°
