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