Question

Craig is cutting a 6 foot square piece of plywood to make a circular tabletop. What will be the circumference of the table? Use 3/14 for pi and round your answer to the nearest hundredth.

Answer 1

Craig is cutting a 6 foot square piece of plywood

Circumference of a circle is

C = 2 x pi x r

Where r = radius

The area of the plywood is

A = 6 x6

A = 36 square units

This implies that each length of the plywood is 6

Length = Diameter of the circle

Diameter of a circle = 2 x r

Diameter = 6

6 = 2 x r

6 = 2r

Divide both sides by 2

6/2 = 2r/2

r = 3 foot

Since, C = 2 x pi x r

C = 2 x 3/14 x 3

C = 2 x 3 x 3 / 14

C = 18/14

C = 1.29 foots

The answer is 1.29 foots
