Answer:
the arc length is 555.17 cm
Step-by-step explanation:
The equation to solve for the arc length is: s = rΘ, where r represents the radios and the Θ represents radians. In order to solve this you need to convert degrees into radians with the formula: radians = degrees ·
You want to find the distance the golf club travels when the golfer swings the club.
First you need to subtract 25° from 360°
360° - 25° = 335°
now you need to convert 335° into radians
radians = degrees ·
radians = 335° · you multiply 335° by
radians = 335/180 then you simplify
radians = 67/36
335° = 67/36
Now we plug everything we know into the equation s = rΘ
s = rΘ
s = 95 (67/36) first multiply 67 by 3.14
s = 95 (210.38/36) divide 210.38 by 36
s = 95 (5.843888889) and multiply 95 by 5.843888889
s = 555.1694444 *remember to simplify to the nearest hundredth
s = 555.17 cm

Answer:
The answer is (B) ⇒ Yes. AB is parallel to CD and AD is parallel to BC
Step-by-step explanation:
<em>There is an important fact about the parallel lines: </em>
- Parallel lines have equal slopes
<em>The rule of the slope of a line is:</em>
, where
and
are two points on the line
<em>Let us use the fact and the rule to solve the question</em>
∵ ABCD is a quadrilateral
∵ A = (0, 2) , B = (2, 6), C = (9, 6), D = (7, 2)
∵ The opposite sides are AB, CD and AD, BC
Find the slopes of the four sides to check the parallel sides
∵
∵
∵ The slope of AB = The slope of CD
∴ AB // CD
∵
∵
∵ The slope of AB = The slope of CD
∴ AD // BC
The correct answer is:
Yes. AB is parallel to CD and AD is parallel to BC ⇒ (B)
