A circle.
You don't even need the words " ... at the center of the figure".
A circle.
the set of points equidistant from a fixed point
Sphere
The perimeter is the sum of all of the sides of the figure. So, simply add up ALL the sides to discover what the perimeter is.
You can not buy an annuity value calculator. It is a tool used in the financial industry to figure out future values or fixed payments. You can use a scientific calculator to figure this out. Just key in the correct formula and you will have your answer.

A circle is a plane figure consisting of a curve in which every point is equidistant from a fixed point called the center.
A circle.
A plane curve all equidistant from a given fixed point, the center.
A sphere is a solid figure in which every point is equidistant from a fixed point called the center.
The distance from the fixed point at the center of a circle to any point on the curve is called the radius.
It is a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
A circle is a closed curve where all points are equidistant from a fixed point called the center. It is a two-dimensional shape with no corners or edges.
The center of the circle. That's how the circle is defined. (The collection of all points on a plane equidistant from a fixed point. The fixed point is the center and the fixed distance is the radius.)
Most likely sinusoid.

It could be a circle or a sphere
