Find The Arc Length Of AC Round Your Answer To The Nearest Tenth class=

Sagot :

Answer:

The arc length is

Step-by-step explanation:

2πr(angle/360)

segment Bc is the diameter which means it's also supplementary.

If it's supplementary it should be 180 degrees.

Currently we know that arc AB is 30 degrees

180 - 30 = 150 degrees

angle ADC = 150 degrees.  

plug in 150 in the angle it should be like 2πr(150/360).

the diameter is 7in and to find the radius it would be half of 7 which is 3.5in

2π(3.5)(150/360) = 9.1630

Make sure to round.

Final answer: 9.2cm
