The radius of the first circle is 17 cm, and the radius of the second circle is 6 cm larger. How many centimeters is the diameter of the first circle less than the diameter of the second circle.
To solve this problem, remember that the diameter is equal to the sum of two radii. Let’s calculate the diameter of the first circle, knowing that the radius is 17 cm.
d = 2 * r = 2 * 17 = 34 cm.
Let’s calculate the radius of the second circle.
17 + 6 = 23 cm.
Let’s calculate the diameter of the second circle.
d2 = 2 * r2 = 2 * 23 = 46 cm.
46-34 = 12 cm.
Answer: the diameter of the first circle is 12 cm less than the diameter of the second circle.
