Solution:
<u>Step-1: Find the area of the pizza.</u>
- Area of pizza = πr²
- => πr² = π x 9 x 9
- => 81π = Area of pizza
<u>Step-2: Find the area of the slice.</u>
- = 81π/6 = Area of slice
- => 27π/2 = 13.5π = Area of slice
Option D is correct.
Answer:
Figure A is scalene and probably obtuse.
Figure B is scalene and right.
Figure C is equilateral and acute.
Figure D is isosceles and right.
Figure E is isosceles and acute.
I am so sorry if I did a few wrong, I'm in Middle-School so I don't know much. I hope I get everything correct!
BPD = 1/2(BD + CA)
BPD = 1/2(70 + 170)
BPD = 1/2(240)
BPD = 120
A full circle = 360 degrees
BC + AD = 360 - 70 - 170
BC+ AD = 360 - 240
BC + AD = 120
