Question

Find the circumference and area of a circle with a diameter of 14 inches. Leave your answers in terms of pi. (4 points)  
C = 14π; A = 49π
C = 7π; A = 28π
C = 14π; A = 28π
C = 7π; A = 49π

Answer 1

Given:
diameter = 14 inches
radius = 14 inches / 2 = 7 inches

Circumference of a circle = 2 π r = 2 * π * 7inches = 14 inches * π

Area of a circle = π r² = π * (7in)² = π * 49in² 

C = 14π    and   A = 49π

Answer 2

Answer:

C = 14π; A = 49π
