Step-by-step explanation:
A
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 12 , then radius = 12 ÷ 2 = 6 , then
A = π × 6² = 3.14 × 36 = 113.04 m²
B
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
Here C = 28.26 , then
2πr = 28.26 ( divide both sides by 2π )
r = = = 4.5 in

Answer:
well 0
Step-by-step explanation:
basically when a point lies on an axis,one of its coordinates must be zero,let's say point a-
if you look at how far the point is from the origin along the x-axis,the answer is zero,therefore the x-coordinate is zero,any point that lies on the y-axis has an x-coordinate of zero.
A because if you use T3 it wouldn’t have make sense so only reasonable and solution that works is A
