Answer:

πr^2

Step-by-step explanation:

My 11th grade teacher taught me this song to remember the formula for area and circumference of a circle (to the tune of "Twinkle Twinkle Little Star"):

"Twinkle twinkle little star circumference equals 2πr. Area if you ever cared always equals πr^2."

What is the value of x?
pickupchik [31]

The angles are congruent meaning that you can set them equal to each other:

26 = 5x + 11

Now you can solve for x

26 - 11 = 5x + (11 - 11)

15 = 5x

15/5 = 5x/5

x = 3

Hope this helped!
