Could someone help, please?

Answer:

Option B

Step-by-step explanation:

By using geometric mean theorem in the given right angle triangle RST,

$\frac{RT}{ST}=\frac{ST}{VT}$

$\frac{RV+TV}{ST}=\frac{ST}{TV}$

$\frac{4.1+10.2}{ST}=\frac{ST}{10.2}$

ST² = 10.2 × 14.3

ST = $\sqrt{145.86}$

ST = 12.077

ST ≈ 12.1

Therefore, Option B will be the correct option.

Circle M is circumscribed about right triangle ABC with legs 6 meters and 8 meters.

pashok25 [27]

ABC is a right triangle, so AC has length given by

$AC^2=(6\,\mathrm m)^2+(8\,\mathrm m)^2\implies AC=\sqrt{100\,\mathrm m^2}=10\,\mathrm m$

Then the circumference of circle M is $10\pi\,\mathrm m$ .
