Relationship between radius and area of a circle is nonlinear. Area = pi * radius^2, so it is like a quadratic. If you graphed radius on the horizontal, and area on the vertical, it would be a parabola (actually a half of a parabola, since you cannot have a negative radius).
The relationship between a circle's radius and it's area is: a = πr2 so if the radius of the circle increases by 7 times, the area will increase by π72 times, or 49π, which is approximately equal to 153.938
A tangent line is always perpendicular to the radius.
I don’t know
The relationship between the area of a triangle and a rectangle is a Triangle is base times height divided by 2. Area of a rectangle is length times height.
The relationship between the radius and area of a circle is as follows: Area of circle = 3.14 x Radius x Radius or 22/7 x Radius x Radius
Pi and the radius can be used to find the area (PiR^2) or the circumference (2RPi) of a circle, where R is the radius.
area = pi*r2 where pi is the irrational number approximated by 3.14159

It depends on the relationship between the rectangle and the circles.
Area = 3.1 times (radius)2 The factor of '3.1' is the number we decided to substitute in place of 'pi' in order to make the relationship approximate, rather than exact.
The relationship between the radius and the diameter of a circle is that: radius = diameter /2
area of a circle = area of a rectangle(parallelogram) formed by the sectors of circle with pi as length and radius as bradth.
The area of a circle is pi times the square of the radius. Pi has no relationship with the area of a polygon.
The relationship between a circle's radius and it's area is: a = πr2 so if the radius of the circle increases by 7 times, the area will increase by π72 times, or 49π, which is approximately equal to 153.938
The relationship between the radius and surface area depends on the shape and that is why some cells are spherical while others are flattened. The greater the SAV ratio of an object, the greater the scope for surface reactions of the object with its surroundings.
The radius is half the diameter of a circle.
