Answer:
Area = 49π
Step-by-step explanation:
circle Area = π x (radius)²
Assuming d = 14 is the diameter (which the problem really should state explicitly, not leave you to assume), then the radius is half of that.
So r = 7, where 'r' is the radius.
Area = π x r² = π(7)² = π(49)
Area = 49π is the exact answer, so it is the one I prefer.
Area = 153.86 is the decimal you get if you multiply 49 x 3.14
Hope this helps.
<span>So we want to know how many students out of 144 practice martial arts every day if we know that 7/12 practice every day. So lets multiply the numerator and the denumerator with 12. We will get (12*7)/(12*12)=84/144. And we got our answer: 84 out of 144 students practice every day.</span>
Answer: A wheel on the outer rail travel 12.57 ft more than a wheel on the inner rail of the track.
Step-by-step explanation:
Since we have given that
Radius of inner circle = 57 ft
As we know the formula for "Circumference of circle":

Since we have also mentioned that there is 2 feet wide circular track for a camera dolly.
So, Radius of outer circle will be given as

So, Distance = Circumference is given by

Hence, Difference between the outer rail travel than a wheel on the inner rail travel is given by

Therefore, A wheel on the outer rail travel 12.57 ft more than a wheel on the inner rail of the track.
Answer:
The correct option is C
C) Hungary
Step-by-step explanation:
Suppose we draw a vertical number line such that it shows elevations of different countries. For y=0, we get India. As all the rest of the values, expect Hungary, are given negative values, hence all the value will lie below India in the numbers line. The only country that lies above India in the number line is Hungary as only it has a positive number for the elevation. So the lowest elevation above 0 will be shown of Hungary which is 78.
Answer:
x = 59 square meters
Step-by-step explanation:
To find x, you must first eradicate the 3 so you can divide. Subtract 3 from both 3 and 121. This should leave you with 118. Then, divide 118 by 2. This will leave you with 59 square meters.
1. 2x + 3 = 121
2. 2x + 3 - 3 = 121 - 3
3. 2x = 118
4. 2x/2 = 118/2
5. x = 59 units
