How many flowers, spaced every 3 in., are needed to surround a circular garden with a 150-ft radius? Use 3.14 for pi.

BARSIC [14]

Answer:

$3,768\ flowers$

Step-by-step explanation:

step 1

Find the circumference of the circular garden

The circumference of the circle is equal to

$C=2\pi r$

we have

$r=150\ ft$

$\pi=3.14$

substitute the values

$C=2(3.14)(150)=942\ ft$

step 2

Convert feet to inches

Remember that

$1\ ft=12\ in$

$942\ ft=942*12=11,304\ in$

step 3

Divide the circumference by 3 in to calculate the number of flowers

$11,304/3=3,768\ flowers$
