Answer:
72.1 cm
Step-by-step explanation:
The arc length formula is s = rФ, where Ф is the central angle and is in radians (not degrees).
Here we convert 140° to radians: 140°(π/180°) = 2.44 radians.
Then the desired arc length is s = rФ = (29.5 cm)(2.44 radians) = 72.1 cm
Hello,
There is a mistake: it is 816 cm² !!! (an area)
length are multiplied by 2,
so area are mutiplied by 2²=4
Area B=816*4=3264 (cm²)
Answer:
7.8
Step-by-step explanation:
First I will try 50. I got 127,550, so that was way too big.
Let me try a smaller number. How about 5. I got 155, so that was a bit too small.
Now I'll try 20. I got 8420. Looks like the number is between 5 and 20.
How about 7. I got 399.
Let me try 8. I got 584! That's really close. It's just a little too big.
I tried 7.5, and got 485.624. So close! Just a little higher.
Putting in 7.8 yields <u>543.192!</u> That's our answer.
<h2><u>Complete Question: </u></h2>
Learning Task 1: Identify similar and dissimilar fractions. On your note- book write S if the fractions are similar and D if dissimilar.
1.
2.
3.
4.
5.
<h2><em><u>The answers:</u></em></h2>
1. - Similar (S)
2. - Similar (S)
3. - Dissimilar (D)
4. - Dissimilar (D)
5. - Dissimilar (D)
Note:
- Similar fractions have the same denominator. i.e. the bottom value of both fractions are the same.
- Dissimilar fractions have different value as denominator, i.e. the bottom value of both fractions are not the same.
Thus:
1. - They have equal denominator. <u><em>Both fractions are similar (S).</em></u>
2. - They have equal denominator. <em><u>Both fractions are similar (S).</u></em>
3. - They have equal denominator. <em><u>Both fractions are dissimilar (D).</u></em>
4. - They have equal denominator. <u><em>Both fractions are dissimilar (D).</em></u>
5. - They have equal denominator. <em><u>Both fractions are dissimilar (D).</u></em>
Therefore, the fractions in <em><u>1 and 2 are similar (S)</u></em> while those in <em><u>3, 4, and 5 are dissimilar (D).</u></em>
