How many flowers, spaced every 3 in., are needed to surround a circular garden with a 100-ft radius? Use 3.14 for pi.

2512 flowers

Step-by-step explanation:

We need to find the circumference first

C = 2 * pi * r

C = 2 * 3.14 * 100

C = 628 ft

We need to convert this to inches

628ft * 12inches/ft =7536 inches

We want the flowers  every 3 inches, so we divide by 3

7536/3 =2512

We need 2512 flowers

c is the answer

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
