Answer:
slice priced $1.50 is better value
Step-by-step explanation:
Angles around a point add up to 360°
Area of a circle = πr²
360° ÷ 60° = 6
⇒ This slice is 1/6 of the whole pizza
⇒ area of the slice = (1/6)π × 6² = 6π in²
⇒ $1.50 ÷ 6π = $0.079577... per in²
360° ÷ 45° = 8
⇒ This slice is 1/8 of the whole pizza
⇒ area of the slice = (1/8)π × 7² = (49/8)π in²
⇒ $1.70 ÷ (49/8)π = $0.088347.. per in²
Therefore, the slice priced $1.50 is cheaper per in²
