Answer:
π (x + 3) inch OR 3.14x + 9.42 inch
Step-by-step explanation:
Diameter (d) = x + 3
Circumference of a circle = πd
=》Circumference of a circle = π (x + 3) inch
If π = 3.14, then,
Circumference = 3.14 (x + 3)
Circumference = 3.14x + 9.42 inch

Answer:
Megan travelled at 9mph for 6 hours and 7mph for 3 hours
Step-by-step explanation:
Speed = distance / time
Speed*time = distance
Assuming that Megan travelled x hours at 9mph
(9*x) + (7*(9-x)) = 75
x = 6 hours
So Megan travelled at 9mph for 6 hours and 7mph for 3 hours
200,000+ 70,000+ 7,000+ 100+ 80
