Try Photo math i guess answer
Circumference of a circle = 2π r (2 * π * radius) or πd (π * diameter)
It's C because for the perpendicular line, you need to construct cross points to draw it through.
- you start by drawing a random circle with F as the center, just as long as it intersects line DE
- Then you use the intersections of that circle to draw new circles starting at F.
- These new circles intersect at F and another point below DE.
- You draw the perpendicular line through F and the other point.
