Step-by-step explanation:
Answer:
A = 15π in²
Step-by-step explanation:
If two of the central angles are 80° and 130°, totalling 210°, then the third central angle must be (360° - 210°), or 150°.
Let's calculate the area of the entire pizza, whose diameter is 12 in and whose radius is therefore 6 in:
A = πr² → A = π(6 in)² = 36π in².
The area of the largest slice, the one with central angle 150°, is
(150/360) times the total area of the pizza:
A = (150/360)(36π) in², or 15π in²
Answer: 15:25
Step-by-step explanation: the number of people is 15 and the area would be 25
