The first circle has a radius of 5 cm. And the second circle has a diameter of 8 cm. Which circle has a larger diameter and how many centimeters is larger?
To solve this problem, remember that the diameter is equal to the sum of two radii. d = 2 * r = r + r. Knowing that the radius of the first circle is 5 cm, we find its diameter.
d = 2 * 5 = 10 cm
The diameter of the second circle is 8 cm, let’s compare them.
10cm> 8cm
10-8 = 2 cm
Answer: the diameter of the first circle is 2 cm larger.
