Answer:25.13
Step-by-step explanation:
I have to assume that figures OAT and OBT are congruent.
If that is true, the center angle O (of the sector AOB= is 120° and the angle of the sector ACB is 360° - 120° = 240°
Now you can state that the circumferece of the circle / 360 ° = arc ACB / 240° and solve for arc ACB.
arc ACB = circumference * 240 / 360 = 2πr *240/360 = 2π(6)*240/360 = 25.13
Answer: option A. 25.13

Answer:
Step-by-step Solution:
<u>Isolate the variable x to get the answer.</u>
- x − 2/5 = −1
- => x = -1 + 2/5
- => x = -1 + 0.4
- => x = -0.6
Hence, the value of x is -0.6.
Hello there,
First you need to add together the numbers.
4+5+9 = 18
Divide the total by this,
180 / 18 = 10
Multiply each number by 10.
40:50:90.
