Answer:
a=19.6 inches^2
Step-by-step explanation:
The area of a circle can be found using
a=πr^2
We know the radius is 2.5, so we can substitute it in for r
We can also substitute 3.14 in for π
a=(3.14)*(2.5^2)
a=(3.14)*(6.25)
a=19.625
Round to the nearest tenth
a=19.6 inches^2
in this case, s is 5 years older than luke's age
Answer:
