Answer:
12 pieces
Step-by-step explanation:
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
To solve this, you just divide 20 divided by 7.
20/7 = <span>2.85714285714
If you are trying to round to the nearest tenth, the next decimal place (hundredths) is a 5, so you must round 2.8 up one more digit.
Your final answer is that</span> 20/7 = 2.9 when rounded to the nearest tenth.
