Answer:
C
Step-by-step explanation:
r=5t
r squared=25t squared
area=pi r squared
so, A(r(t))=25(pi)(t squared)
Answer:I would do the same thing which is copy and paste because its very
difficult to find out how to do it but ill keep trying

Answer:
120.105m^2
Step-by-step explanation:
Given data
Diameter of circular bed= 24+3m = 27m
radius= 27/2= 13.5
m
Diameter of side walk = 12
radius= 24= 12
m
Hence the area of the sidewalk is
Area= area of circular bed- area of side walk
Area=πR^2-πr^2
Area=π(R^2-r^2)
Area=π(13.5^2-12^2)
Area= 3.14(182.25-144)
Area= 3.14(38.25)
Area=120.105m^2
Hence the area of the side walk is 120.105m^2
