Question

A circular table has a circumference of 5 feet. Find a the circumference of the table and b the area of the table use 3.14 for pi

Answer 1

The circumference is;

`31.4\text{ ft}`

The Area is;

`78.5\text{ }ft^2`

Step-by-step explanation:

Given a circular table of radius 5 feet;

`r=5\text{ ft}`

Recall that the formula for Area and Circumference of a circle can be written as;

`\begin{gathered} A=\pi r^2 \\ C=2\pi r \end{gathered}`

where;

A = Area

C = Circumference

pie = 3.14

solving for the Area and the circumference;

`\begin{gathered} A=\pi r^2 \\ A=3.14*5^2 \\ A=78.5\text{ }ft^2 \end{gathered}`
`\begin{gathered} C=2\pi r \\ C=2*3.14*5 \\ C=31.4\text{ ft} \end{gathered}`

Therefore;

The circumference is;

`31.4\text{ ft}`

The Area is;

`78.5\text{ }ft^2`
