The diameter of a circle is 14 in. Find its area in terms of <br> π<br> π.

maksim [4K]

Answer:

49π in²

Step-by-step explanation:

Step 1: Find the radius.

To find radius given diameter, just divide the diameter by 2: $\frac{14}{2}$
14/2 = 7, so the radius is 7.

Step 2: Apply area of circle formula.

The formula to find the area of a circle is πr², where r = radius.
Now, plug in the value of r: π(11)².

Step 3: Simplify.

π(11)²
π(121)
121π

Since we're finding the area in terms of pi, we don't have to multiply 121 by pi, so the answer is 49π in².

What are the roots of the quadratic equation below 3x2+15x-5=0

fomenos

Answer:

Step-by-step explanation:

$3x^2+15x-5=0\\a = 3\\b = 15\\c = -5\\ x = -b\±\frac{\sqrt{b^{2} -4ac} }{2a} \\x = -(15)\±\frac{\sqrt{15^{2} -4(3)(-5)} }{2(3)} \\x = -15 \±\frac{\sqrt{225+60} }{6} \\x = -15\±\frac{\sqrt{285} }{6} = A$
