the arc length is calculated by the formula
then
or it can be calculated using the circumference of the circle since we have a semicircle the circumference 2πr must be divided by 2 С=2πr:2=πr =8π=<u>25,12</u>
They will have same amount in 45 weeks.
Step-by-step explanation:
Given,
Starting amount of Nancy = $425
Per week saving = $25
Let,
x represent the number of weeks.
N(x) = 25x+425
Starting amount of Seamus = $875
Per week saving = $15
S(x) = 15x+875
For same amount;
N(x) = S(x)

Dividing both sides by 10

They will have same amount in 45 weeks.
