Step-by-step explanation:
If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter
hope that helps!
Kylie can add 6 books more to fill the box.
Step-by-step explanation:
Given,
Weight limit of each box = 6kg
1 kg = 1000 grams
6 kg = 1000*6 = 6000 grams
Weight limit of each box in grams = 6000
Weight of each book = 750 grams
Already picked weight = 1500 grams
Let,
x be the number of books she can add.
Weight of one book*number of books + Already packed weight = Weight limit of each box in grams
750x + 1500 ≤ 6000

Dividing both sides by 750

Kylie can add 6 books more to fill the box.
