Answer:

area of a circle = pi*r^2

3 = pi*r^2

r^2 = 3/pi

r = √(3/pi)

diameter = 2*r = 2*√(3/pi)

A delivery to the flower shop is recorded in the chart above. The shop makes centerpiece arrangements using 36 flowers that are

Alchen [17]

Answer:

yes, they will be able to make at least 10 arrangements using each type of flower

no, they will not be able to make 100 arrangements using each type of flower.

Step-by-step explanation:

Explain your thinking: The shop makes arrangements with only the same type of flower. We know that each arrangement requires 36 flowers. By analyzing the data, we can see how many arrangements they can make based on each flower type.

There are 580 tulips - and we need 36 per arrangement

580/36= 16 arrangements of tulips

There are 2,410 daisies

2410/36= 66 arrangements of daisies

There are 4,000 carnations

4,000/36= 111 arrangements of carnations.

Since there are at least 10 arrangements per set of flowers, the first statement is true (we CAN make at least 10 arrangements using each type of flower)

Since there is only 16 arrangements for tulips and 66 for daisies, we CANNOT have at least 100 arrangements per flower type
