Question

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.

Answer 1

C: 7π metersA:

12.25π meters squared

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)
