Problem:
The radii of two circles are 19cm and 9cm respectively. Find the radius of the circle which has a circumference equal to the sum of the circumference of the two circles.

Solution:
To solve this problem, we need to find the radius of a circle that has a circumference equal to the sum of the circumferences of the two given circles. We can do this by using the formula for the circumference of a circle.

Formula:
The formula for the circumference of a circle is given by:
C = 2πr

Given:
The radii of the two circles are:
r1 = 19cm
r2 = 9cm

Step 1: Calculate the circumferences of the given circles:
Using the formula for the circumference of a circle, we can calculate the circumferences of the two given circles.

C1 = 2πr1
C1 = 2 * 3.14 * 19
C1 ≈ 119.32 cm

C2 = 2πr2
C2 = 2 * 3.14 * 9
C2 ≈ 56.52 cm

Step 2: Find the sum of the circumferences of the two circles:
To find the sum of the circumferences, we simply add the two circumferences together.

C = C1 + C2
C ≈ 119.32 + 56.52
C ≈ 175.84 cm

Step 3: Find the radius of the circle with the given circumference:
Now, we need to find the radius of the circle that has a circumference equal to the sum of the circumferences of the two given circles.

C = 2πr
175.84 = 2 * 3.14 * r

Simplifying the equation, we have:
r = 175.84 / (2 * 3.14)
r ≈ 27.97 cm

Answer:
The radius of the circle that has a circumference equal to the sum of the circumferences of the two given circles is approximately 27.97 cm.
