A circle has a radius of 10. An arc in circle has a central angle of 72 what is the length of the arc
BARSIC [14]

Answer:

4π

Step-by-step explanation:

-A circle subtends a total angle of 360 ° from its center.

-The length of an arc is directly proportional to the angle it subtends from the circle's center.

#The arc's length can therefore be calculated as:

C=\pi D=2\pi r\\\\\therefore C=\frac{72\textdegree}{360\textdegree}\times 2\pi \times 10\\\\=4\pi

Hence, the length of the arc is 4π

What is the value of x?<br> Enter your answer, as a decimal, in the box.
RideAnS [48]

Answer:

x = 67.5 ft

Step-by-step explanation:

In ΔNMP

∵ AB // NP

∴ m∠ MAB = m∠MNP

∴ m∠MBA = m∠MPN

∵ ∠M is a comman angle

∴ ΔMAB is similar to ΔMNP

∴ MA/MN = MB/MP

∵ MA = 71.5 - 22 = 49.5

∴ 49.5/71.5 = x/97.5

∴ x = \frac{(49.5)(97.5)}{71.5} = 67.5
