Question

What is the area of a circle with a diameter of 12. 6 in. ? Use 3. 14 for pi and round your final answer to the nearest hundredth. Enter your answer in the box. In².

Answer 1

124.63 in² (to the nearest hundredth)

Explanation:

• Area of a circle =
  `\pi r^2` (where r = radius)
• Radius = half of diameter

For this problem:

`\pi`= 3.14

`r` = 12.6 ÷ 2 = 6.3

Therefore, area = 3.14 x 6.3²

= 124.6266

= 124.63 in² (to the nearest hundredth)
