Find the area and the circumference of a circle with diameter 7 m. Use the value 3.14 for it, and do not round your answers.

C: 7π metersA: 

12.25π meters squared

Step-by-step explanation:

Circumference: dπ or 2πr (d is the diameter and r is the radius, which is half the diameter)

Area: πr2

Circumference: 7π meters (if you use an approximation such as 3.14 for π, multiply that by 7)

Area: (72)2π

Area: 12.25π meters squared (if you use an approximation such as 3.14 for π, multiply that by 12.25)

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
