It is a semicircle so you'd use this formula for the area:
πr² / 2
Then substitute 2 into r and solve (2 because it's the radius, 4 is the diameter)
You would use this formula for the perimeter:
(πd / 2) + d
or
πr + 2r
Then substitute 4 into d / 2 into r and solve.
Hope I helped :)

second one listed
Step-by-step explanation:
second one given--he can buy between 3 and 6 albums; and 0 to 30 songs

2014-1863=151
151/4=37.75 round up 38 possible presidents since Lincoln based on 151 years
142/4=35.5 round up 36 possible presidents since Lincoln based on 142 years
