How many flowers, spaced every 4 in., are needed to surround a circular garden with a 125-ft radius? Use 3.14 for pi

Vesna [10]

Answer:

2356 flowers

Step-by-step explanation:

The number of flowers will be given by

F=1+p/s

Where p is perimeter and s is rhe spacing

Perimeter of a circle is given by

$P=2\pi r$

Where r is the radius of the garden.

Substituting 125 ft for radius, rhe perimeter will be

$P=2*3.14*125=785 ft$

Conversion

Converting ft to inches, we multiply ft by 12 hence 785*12=9420 inches

Number of flowers will then be

F=1+9420/4=1+2355=2356 flowers
