The Circular Surface Of A Table Has A Diameter Of 4 Feet. What Will It Cost To Have The Top Refinished If The Company Charges $5 Per Square Foot For The Refinishing? Use 3.14 For And Round Your Answer To The Nearest Cent.
Answer:
Apparently the table is circular
so the area of a circle is
A=pi*r2
we are given that
diameter = 4 feet
so radius would be half of that
r=d/2
So
r=4/2
r=2
So plugging within these values in the formula for the area
A=3.14*22
A=3.14*4
A=12.56
We have to find the cost
we are given
1 square foot --- $5
we own
12.56 square feet ---$x
cross multiplying
1(x)=5(12.56)
multiplying
x=62.8
So it would take the company $62.8
