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

Answer:

The circumference is;

$31.4\text{ ft}$

The Area is;

$78.5\text{ }ft^2$

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\times5^2 \\ A=78.5\text{ }ft^2 \end{gathered}$$\begin{gathered} C=2\pi r \\ C=2\times3.14\times5 \\ C=31.4\text{ ft} \end{gathered}$

Therefore;

The circumference is;

$31.4\text{ ft}$

The Area is;

$78.5\text{ }ft^2$
