Answer:
A ≈ 158.37km²
Step-by-step explanation:
<u>Using the formulas</u>
A=πr2
d=2r
<u>Solving forA</u>
A = 1
/4πd 2
= 1
/4·π·
14.22 ≈ 158.36769km²
Therefore, the are of the circle in nearest hundredth is A ≈ 158.37km²
10/24 or 5/12 is the answer
Answer:
0.722
Step-by-step explanation:
First of all add up the sections 1 to 8 to make sure they add to 360
They do actually.
- 1 10
- 2 20
- 3 30
- 4 40
- 5 50
- 6 60
- 7 70
- <u>8 80</u>
Total 360
This is an area question. Every time you spin the spinner, it must come to an area labeled 1 to 8.
You could do this by setting up a ratio of each section and subtract the section for 3 and 7. That's the long way.
The shorter way is to add up the degrees for 3 and 7 and subtract them from the total (360)
Area 3 + area 7 = 30o + 70o = 100 degrees.
So the probability of landing in 3 or 7 is 100 / 360 = 0.278 (rounded)
The probability of Not landing on 3 or 7 is 1 - 0.278 = 0.722
If this value was compounded in 5 years, then we are going to use the compound interest formula to solve it.
A = p(1+r%)∧n
Where A⇒ Amount accumulated for the entire period.
p⇒ Money invested
r⇒ Interest rate per year
n ⇒ period the money was invested.
∴A = 5000(1+4/100)∧5
The exponential function is A=5000×1.04∧5
A=5000×1.04∧5
=5000×1.216652902
=6,083.264512
The amount after 5 years = $6,083.26
The answer is going to be 19.505? hope that helped
