What is the arc length if the central angle is 225 degrees and the radius of a circle is 3 cm
Answer:2*225*pie/360*3
Step-by-step explanation:
The required length of the arc is 11.78cm
Angle θ = 225 degrees
radius = 3 cm
arc = ?
What is an arc?
Arc is the measure of angle on the circumference of circle.
Length of an Arc = θ × (π/180) × r
Length of an Arc =225 × (π/180) ×3
= 11.78
Thus, the required length of the arc is 11.78 cm

She completed the following actions to construct the angle bisector of ZABC, but made a mistake in one of the steps. Select the step in which
her mistake was made.
Step 1: She placed the compass on point B and drew an arc which intersects ray BA at point D and ray BC at point E.
Step 2: Next, she placed the compass on point D and drew an arc on the interior of ZABC.
Step 3: Then, she placed the compass on point C and drew an arc on the interior of ZABC, which intersects the previous arc.
Step 4: She labeled the intersection of the two arcs as point F and drew the ray BF, which represents the angle bisector
of ZABC.
The angles formed by the angle bisector BF are ∠FBA and ∠FBC.
The step in which the mistake was made is step 3; Then, she placed the compass on point C and drew an arc on the interior of ∠ABC which intersects the previous arc.
Reasons:
The steps to draw an angle bisector are;
Place the compass at the vertex of the angle and draw an arc intersecting the the two rays forming the angle at points D and E
Place the compass at point D and draw an interior arc to the given angle
Place the compass at point E and draw a second interior arc intersecting the previous arc
The point of intersection of the two arcs can be labelled F and joined to the vertex of the given angle to complete the angle bisection
Therefore, the step in which the mistake was made is; Step 3 where the compass is placed at point C rather than point E to draw the second arc of the angle bisector

A company makes 140 bags.
30 of the bags have buttons but no zips.
27 of the bags have zips but no buttons.
20 of the bags have neither zips nor buttons.
A bag is selected at random.
What is the probability that the bag has buttons?
Answer: 41/75 or 54.67%
Step-by-step explanation:
Buttons --- yes, zips --- yes = 45 (compute as 150 - 37 - 45 - 23)
Buttons --- yes, zips --- no = 37
Buttons --- no, zips --- yes = 45
Buttons --- no, zips --- no = 23
Therefore, 82 out of 150 bags have buttons so probability = 82/150 = 41/75

Lisa paint 3/8 of the room and Madison paint 1/5
how much more of the room did Lisa paint
Answer:
[tex]\huge\boxed{\frac7{40}\ more\ of\ the\ room}[/tex]
Step-by-step explanation:
To solve this problem, you need to find the common denominator.
To do this, simply multiply the first fraction by 5/5, and the second by 8/8 to get:
[tex]\frac15=\frac{1}{5}*\frac{8}{8} = \frac{1*8}{5*8} = \frac{8}{40}[/tex]
[tex]\frac38=\frac38*\frac55=\frac{3*5}{8*5}=\frac{15}{40}[/tex]
Thus, Lisa painted 7/40 more of the room than Madison.
