A. for the circumference it is C=pi(d)=pi(2r)=pi(10)= 31.4 ft
b. for the area it is A=pi(r)^2=pi(5)^2=pi(25)= 78.5 ft squared
c. since the are is 78.5 ft squared multiply by $4.50= $353.25 to floor the circle.
Answer:
i belive its 1
Step-by-step explanation:

Answer:
C
Step-by-step explanation:
This is because using the formula of area for shapes, you get this equation
A=2(wl+hl+hw)=2·(4·6+4·6+4·4)=128
