A contractor has been hired to install flooring for a bandstand in the shape of a circle that is 21 feet across. How many square

SOVA2 [1]

Answer:

A. 346.19 square feet.

Step-by-step explanation:

We have been given that a contractor has been hired to install flooring for a bandstand in the shape of a circle that is 21 feet across.

To find the square feet of flooring required, we will find area of circle.

Since the length across the circle is 21 feet, so radius of circle will be half of 21 feet.

$\text{Radius}=\frac{\text{21 feet}}{2}$

$\text{Radius}=\text{10.5 feet}$

$\text{Area of circle}=\pi r^2$

$\text{Area of circle}=\pi (\text{10.5 feet})^2$

$\text{Area of circle}=3.14*110.25\text{ feet}^2$

$\text{Area of circle}=346.185\text{ feet}^2$

$\text{Area of circle}\approx 346.19\text{ feet}^2$

Therefore, 346.19 square feet of flooring will be required.
