Answer: 0.73
Step-by-step explanation:
Step-by-step explanation:
all work is shown and pictured
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.
F - 12 = -35
f - 12 + 12 = -35 + 12
f = -23
