Helpp i beg u its due in one hour!!! plz

Answer:

113.1 cm²

Step-by-step explanation:

we are given the diameter of the circle (length is 12 cm), and the formula for the area of the circle, which is πr², where r is the radius

so first, we need to find the radius

the length of the radius is half the length of the diameter

so that means that r=d/2

r=d/2

r=12/2

r=6

therefore the length of the radius is 6

now square 6, which is the same as multiplying it by itself

6²=36

now, multiply the radius squared by π, which is often substituted for as 3.14 or 22/7

so if we were to do 22/7 for instance,

36*22/7≈113.14

round that to 113.1

there's your answer :)

Hope this helps!

A box of cashews, peanuts, and almonds contains 144 nuts. For every 2 cashews, there are 3 peanuts and 7 almonds. How many more

Rasek [7]

To solve this problem, first we need to find the number of peanuts, cashews, and almonds in the bag...

Total nuts=144

The ratio of cashews to peanuts to almonds can be shown as:

cashews:peanuts:almonds
2:3:7

Now lets add up the numbers in the ratio.

2+3+7=12

So, for every 12 nuts in the bag, 2 are cashews. For every 12 nuts in the bag, 3 are peanuts. For every 12 nuts in the bag, 7 are almonds.

Now lets divide the total number of nuts (144) by the sum of the ratio (12).

144/12=12

Now we can solve for the number of every type of nut in the bag...

Cashews=12*2=24nuts

Peanuts=12*3=36nuts

Almonds=12*7=84nuts

Now we can answer the problem:

Peanuts-cashews=
36-24=12 nuts

Answer: There are 12 more peanuts than cashews.

L.) How do you construct congruent segments, segment bisectors, angles, and angle bisectors using tools such as a compass and a

kondor19780726 [428]

Answer:

Construction of congruent segment: First we take the measurement of the line segment with help of marked scale or a compass, then by pointing the measurements we can get the congruent line segment.

Construction of congruent angle:

Step 1: Make two congruent segments,

Step 2: Adjust compass in a fixed length.

Step 3: Make an angle on any side of one segments with help of compass,

Step 4 : Again, make an angle on any side of the another segment with the same adjusted compass.

Construction of segment bisector,

Step 1: First place the compass on the one end of the segment,

Step 2: Adjust the compass approx to the half length of the segment,

Step 3: Draw arc above and below to the segment,

Step 4: Now, go the other end and by the same length draw two arcs by crossing the previous arcs.

Step 5: join the above and below crossed marks.

Construction of angle bisector:

Step 1: Place the compass on the vertex of the angle,

Step 2: Adjust the compass in any length,

Step 3: Make an arc in one segment of the angle and from that arc again Make an arc above the angle

Step 4: Make an arc of the same length in the another segment by the same vertex and crossed the arc made above the vertex.

Step 5: join the point of crossing and the vertex of the angle.
