What is the area of the following circle?

Mathematics
1 answer:
valkas [14]3 years ago
4 0

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.

Answer: 2.2x * 10^3
You would have to move the decimal place 3 times for 2.2x to get 2,200x, thus you get 10^3.

Hope this helps!

Let's call the first unknown integer x and the second one y.

"Four times an unknown integer"

  • We can write it as 4x

"Multiplied by three times the unknown integer plus a different unknown integer"

  • 4x is multiplied by 3x+y, so 4x(3x+y)=12x²+4xy

"Equals 100."

  • 12x²+4xy=100

And so the answer is C: 12x²+4xy-100=0
