Question

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

Answer 1

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.
