miss Akunina [59]

Answer:  7.5²π   square centimeters.  OR  56.25π cm²

Does a=2.1 b=7.2 c=7.5 form a right triangle
Anna007 [38]

Answer:

Yes

Step-by-step explanation:

If the longest side squared is equal to the sum of the squares on the other 2 sides then they form a right triangle

longest side = 7.5

7.5² = 56.25

2.1² + 7.2² = 4.41 + 51.84 = 56.25

Thus the 3 values form a right triangle.
