The diameter of a table tennis ball is millimeters. What is the approximate surface area of a table tennis ball?

since there is no value for the dimensions of the tennis ball. The tennis ball is a sphere with a Surface Area 4pir²

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

the first one

step-by-step explanation:

just id the test.
