Triangles ABC and XYZ are similar figures, because angles A, B, and C are congruent to angles X, Y, and Z, respectively. If side AC equals 3 cm, BC equals 9 cm, and XZ equals 15 cm, what is the length of side YZ?

45cm

Step-by-step explanation:

Since they are simliar, they are proportional.

SO, you can do AC/XZ = BC/YZ

You can also see that XZ is 5 times larger than AC

SO multiply BC by 5.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

the answer is 21%.
