The sum of the circumference of two circles is 38π cm and the sum of their areas is 193π cm². calculate the radii of the circles.

The radii of the circles are 12 cm and 7cm.

Step-by-step explanation:

Let the radii of the circles be

Given:

Sum of circumference of two circles= 38π cm

Formula for circumference of a circle with radius r = 2πr

------------1

Sum of areas of two circles= 193π cm²

Area of circle with radius r = πr²

-------2

Substituting r2 = 19 - r1 in equation 2 we get:

Then r2 = 19 - r1

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

r and t.

both are 64 degrees.
