For the given central angle, determine the distance traveled along the unit circle from the point (1, 0). 360 degrees a. 6.28 units clockwise c. 3.14 units clockwise b. 6.28 units d. 3.14 units

Answers

Answer:

The length of a 180° arc of a unit circle is π ≈ 3.14 units.

Step-by-step explanation:

Use your knowledge of the circumference of a circle (the length full around) and the fact that there are 360° in the central angle of a full circle. The distance around is proportional to the angle, so an arc of measure 180° will have a length equal to

... (180°/360°) × circumference = (1/2)×circumference

For a unit circle, the circumference is 2π (= π×diameter = 2π×radius). Half that length is π units.

Zac is 18 years old.
The ratio of Zac's age to Ed's age is 2:1.
Tim's age is 2/3 Zac's age.
How old is Tim?

Answers

Answer:

Tim is 12 years

Step-by-step explanation:

Given that Zac is 18 years old and Tim's age is 2/3 Zac's age, to compute Tim's age, we would multiply Zac's age with the fraction.

Such that;

Tim's age = 2/3 * 18

= 2* 18/3

= 2 * 6

= 12 years

Hence Tim is 12 years old.
