The area of a circle given it diameter is

So let answers question 1-4.
1. The area is

2. The area is

3.

4.

where d is the diameter and

where r is the radius.
A circumference of 100 m means the radius is 50 because


So this means the area is

Answer:
A
Step-by-step explanation:
3x^2 - 8x + 4 = 0
x= [-b +or- square root (b^2 - 4ac)] ÷ 2a
= [-(-8) +or- square root (-8)^2 - 4(3)(4)] ÷ 2(3)
= [8 +or- square root 16] ÷ 6
= 2 or 2/3
