The diameter of a circle is 38 in. Find its area to the nearest whole number.
nikklg [1K]

Answer:

1134

Step-by-step explanation:

Formula for diameter=2 x r

(π is 3.14)

Formula for area= π x r^2

So all you basically have to do is go backwords with the first one then plug the radius into the second one normally

38/2=19

Now just plug it into your second equation

π x 19^2=1134.11494795

And lastly round that to 1134, easy! :)

Draw 2 squares. The first one should have an area of 12 square units.The second one should have an area that is DOUBLE that of t
statuscvo [17]

Step-by-step explanation:

Given the information:

  • 1st square:  12 square units
  • 2nd square: DOUBLE that of the first square = 2*12 = 24 square units

From that, we can determine the length of the side in each square:

1/ x^{2} = 12

<=> x = 2\sqrt{3}

2/ a^{2} = 24

<=> a = 2\sqrt{6}

Please have a look at the attached photo.

Hope it will find you well.

John mows 247 square feet of lawn per minute. how many square yards of lawn does he mow per hour?
Black_prince [1.1K]
1647. 1 hour=60 minutes. John can mow 247 square feet per minute, so he can mow 60*247=14820 square feet per hour. 1 yard=3 feet, so 1 square yard =3^2=9 square feet, so in the same duration of time, John can mow 14820/9=1647 square yards (approximately) per hour.
