Answer:
<em>75.408 ft</em>
Step-by-step explanation:
In 20 minutes, the angle swept by a minute hand is calculated as
(20/60) x 360° = 120°
The length of the minute hand = 36 ft
To calculate the distance moved by the minute hand, we solve for the fraction of the circumference of a circle swept by the minute hand in going through this 20 min.
we use the expression
Distance moved by the tip of the minute hand d = (θ/360) x 2πR
where
θ is the angle swept in the 20 minutes = 120°
R is the length of the minute hand, which is the radius of the circle formed if the minute hand moves completely in a 360° motion round the clock.
R = 36 ft
substituting values, we have
d = (120/360) x (2 x 3.142 x 36) = <em>75.408 ft</em>
Answer:
(x - 4)² + (y + 1)² = 25
Step-by-step explanation:
Circle Formula: (x - h)² + (y - k)² = r²
We are given <em>r</em>, and <em>(h, k)</em>, so simply plug them into the formula to get your answer.
1) Y intercept is -5. x is about1.25
2) Y intercept is +2. X is -2
