Answer:
a = 16 π cm² Exact answer
a = 50.24 cm² Decimal approximation
Step-by-step explanation:
Radius of the circle
16/2 = 8
Area of the circle

She will run and swim again on the same day after 21 days.
<u><em>Explanation</em></u>
Juanita runs every third day and swims every seventh day.
For finding the number of days she will run and swim again on the same day, we just need to find the <u>LCM(Least common multiple) of 3 and 7</u>.
As there is no common factor between 3 and 7, so for finding the LCM, we will just multiply 3 and 7.
So,
Thus, she will run and swim again on the same day after 21 days.
