The length of an arc is given by (θ/360)2πr, where θ is the angle subtended by the arc at the center and r is the radius.
The angle θ in this case is 270°, while the radius is 7 feet, diameter is 14 feet
Thus the length of the of the cable will be;
=(270/360)× 22/7×14
= 0.75 × 44
= 33 feet

irga5000 [103]

A)

since she washed 30 plates in 5 mins (7:30 to 7:35) the ratio was 5:30 or in simplest form 1min:6plates

This means she washes 6 plates a min and thus from 7:15 to 7:38 (23 mins) she washes:

6X23 = 138 plates

b)

L - plates left
T- total plates
t - time(mins)

"L = T - 6x"
This is because she washes 6 plates a min
