A circle has a radius of five ft.
a. Find the circumference of the circle.
b.Find the area of the circle.
c.If tile cost $4.50 per square foot, how much will it cost to tile the circle?
Use 3.14 for π

Respuesta :

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.
