Answer:
Step-by-step explanation:
Given diameter (d) = 13 m
circumference
= π * d
= 3.14 * 13
= 40.82 m
Answer:
108 cm^2
Step-by-step explanation:
A= 1/2 b×h
so
1/2 12×18
900 / 60 = 15
So, the plane traveled 360,000 meters in 15 minutes.
Generally, we do per hour. So, 15 mins * 4 = 60 mins or 1 hour. Because we multiplied the time by 4, we also need to multiply the distance by 4. 360,000 * 4 = 1440000 meters. The plane was traveling at 1440000 meters per hour.
However, it does not make sense to use meters for this long of a distance. I am going to convert it into miles (let me know if the question asks for a different unit of distance). 1 mile equals 1609.34 meters. Divide 1440000 by 1609.34 to get how many miles. 1440000 / 1609.34 = 894.7767408.
Therefore, the plane is going about 895 miles per hour--pretty fast!
I believe the correct answer is 45 degrees. The smallest positive angle <span>θ in QI for which tan θ = 1 would be 45 degrees. We obtain it as follows:
</span>tan θ = 1
<span>θ = tan^-1 (1)
</span>θ = 45 degrees
Hope this answers the question. Have a nice day.
