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.

camelback mountain has an elevation change of 1,264 feet. how many pennies would it take to make a stack that high ? show all wo
gtnhenbr [62]

              Camel back Mountain = 15,168 inches (1,264 feet)

  • 1 Penny = 0.061 (.0610) Inches
  • 10 Penny = 0.61 (.610) Inches
  • 100 Penny = 6.1 (6.10) Inches
  • 1,000 Penny = 61 (61.0) Inches
  • 10,000 Penny = 610 (610.0) Inches

                                                   <u>-SOLVING-</u>

10,000 Penny = 610 inches PLUS

1,000 Penny = 61 inches AND 61 inches x 5 = 305 (5,000 Penny)

100 Penny = 6.1 inches PLUS

10 Penny = 0.61 inches AND 0.61 inches x 6 = 3.66 (60 Penny)

1 Penny = 0.061 inches AND 0.061 inches x 8 = 0.488 (8 Penny)

                                            -<u>FINAL ANSWER-</u>

610 + 305 + 6.1 + 3.66 + 0.488 = 925.248 Penny it would take.
