Estelle drew two parallel lines, PQ and RS, intersected by a transversal KL, as shown below: Two parallel lines, PQ and RS, are drawn with KL as a transversal intersecting PQ at point M and RS at point N. Angle KMQ is shown congruent to angle MNS. Which fact would help Estelle prove the measure of angle KMQ is equal to the measure of angle MNS? When both angle KMQ and angle MNS are equal to angle RNM, the angles KMQ and MNS are congruent. When same-side, consecutive interior angles QMN and PMN are complementary, the angles KMQ and MNS are congruent. When alternate interior angles QMN and MNR are supplementary, angles KMQ and MNS are congruent. When both angles KMQ and MNS are equal to angle PMN, the angles KMQ and MNS are congruent.

Find the area of a circle with a diameter of 56 millimeters. Round your answer to the nearest hundredth.
area: about ???
mm2
Answers
9514 1404 393
Answer:
2463.01 mm²
2461.76 mm² if you use 3.14 for π
Step-by-step explanation:
The formula for the area of a circle is ...
A = πr²
where r is the radius, half the diameter.
For a diameter of 56 mm, the radius is 28 mm. Using that in the formula gives an area of ...
A = π(28 mm)² = 784π mm²
For an appropriate value of π, the area is ...
784π mm² = 2463.00864... mm² ≈ 2463.01 mm²
For 3.14 as the value of π, the area is ...
784(3.14) mm² = 2461.76 mm²
_____
Comment on pi
Quite often these problems expect you to use 3.14 for pi. The required answer has 6 significant digits, so the use of a 3-digit value for pi is not appropriate. Rather, the value used should be 3.141493 or even more accurate.

If the diameter of a circle is 12, what is the area and circumference?
Answers
Answer:
circumference: 37.7
area: 113.1
Step-by-step explanation:
for the future look up '___ of a circle'
and enter the radius (if u are given the diameter divide it by 2)
Answer:
circumference = 37.68 (37.7 if you're rounding it)
Area = 113.04 (113.1 if you're rounding it)
Step-by-step explanation:
The formula for circumference is C=2πr (2 times pi times radius)
If the diameter is 12, the radius is 6.
2 x 3.14 x 6 = 37.7
The formula for area is A=πr2 (pi x radius to the second power)
The radius is 6. Six to the second power is 36.
36 x 3.14 = 113.04

Subtracting a negative is the same as adding a positive, since the negatives cancel each other out.
So, 7/8 - (-1/8) is the same as 7/8 + 1/8. Adding 1/8 to 7/8 gives you 8/8, or one whole, so your answer is D. 1!

( I am assuming that these are all fractions)
1. 14 [tex]\frac{4}{7}[/tex]
2. 8
3. [tex]\frac{4}{15}[/tex]
4. 5 [tex]\frac{8}{11}[/tex]
Step-by-step explanation:
1. First you have to convert 15 into a fraction but it must have the same denominator causing the equation to look like 105/7 - 3/7= 102/7. But you cannot just leave the fraction like that it must be simplified 14 [tex]\frac{4}{7}[/tex]
2. Three-fifths of an hour is 36 minutes. You would next multiply 5 by 60 which would the hours into minutes 5 x 60 = 300. You would then divide 300 by 36 which would give you 8.3333333333, which I just simplified it to 8
3. In order for you to multiply a fraction you would first multiply the top then the bottom. 12 x 6= 72, 15 x 18= 270. The fraction would look like 72/270 which is simplified to [tex]\frac{4}{15}[/tex] .
4. First I changed the fractions into improper fractions causing the fraction to look like 36/8 x 14/11 (I got these answers by 8 by 4 then adding 4, then for the next fraction I multiplied 11 by 1 then added 3.) 36 x 14= 1224, 11 x 8= 88 the fraction would look like 1,224/88 you would simplify to 5 [tex]\frac{8}{11}[/tex]
