Question

You have a table in your living room with a round top that has a diameter of 2 1/2 feet. You would like to put a piece of glass over the top of the table to protect the surface. What is the area of the table top? (Use 3.14 for the value of pi). Write your answer as a mixed number.

1 49/100 square feet

Answer 1

The area of circle is given by,
A = pi*(D^2)/4
where
D = diameter
Substituting,
A = ( 3.14 * (5/2)^2 )/4
A = 4.90625 ft^2
In mixed number, this is 4 29/32 ft^2.

Hope this helps :3
