25π cm ≈ 78.54 cm
Step-by-step explanation:
The diameter of the circumscribing circle is the diagonal of the rectangle.
You may recognize the rectangle dimensions as the numbers in the (7, 24, 25) Pythagorean triple. If not, you can compute the diagonal length from ...
d = √(7²+24²) = √(49+576) = √625 = 25 . . . . centimeters
The circumference of the circle is π times the diameter:
C = πd = 25π cm
Answer:
2y^2+18x
Step-by-step explanation:
4y^2 + 6x -2y^2 + 12x
=4y^2-2y^2+6x+12x
=2y^2+6x+12x
=2y^2+18x
