Answer:
Area: 7850 square cm
Perimeter: 314 cm.
Step-by-step explanation:
The area is 
. With r=50, 
=2500π which is about (2500)(3.14)=7850.
The perimeter is 
which is the same as (diameter)(π). The diameter is 100, so 
which is about (100)(3.14)=314.
Answer:
2
Step-by-step explanation:
2 distinct real number zeros
Step-by-step explanation:
The discriminant b^2 - 4ac
= (-17)^2 - 4*4*3
= 241
So it has 2 distinct roots.
I dont really know... I will figure it out.
Point c because its the top and they rotated it to it's side
