Question

Rafael is building a circular table with a diameter of 2.5 feet. The wood costs $32.50 per square foot. How much will it cost Rafael to make the table? Use 3.14 to approximate π. Enter your answer in the box.

Answer 1

$159.45

Explanation:

In this case, the formula for the area of a circle is 3.14*r²

3.14*1.5625=4.90625‬

4.90625*32.50=159.453125

It will cost $159.453125‬ or about $159.45

Answer 2

$159.45

Explanation:

diameter of the table = 2.5 feet

radius of table = 2.5/2 = 1.25

Hence area of the circular table = πr²

= 3.14 x 1.25²

= 4.9 feet²

Given rate of wood = $ 32.5 per square feet

rate of 4.9 square feet wood = 32.5 x 4.9

= $ 159.45
