Let a circle inside triangle DEF have a radius = 3, and let it
be tangent to EF at point Z. Suppose |EZ| = 6 and |FZ| = 7. What
are the lengths of d, e, and f?
Consider a wire of uniform density and mass M shaped into a
quarter circle of radius R.The wire is located in the xy plane,
with the origin at the focus of the quarter circle (i.e at the
center of the circle of which the wire is part). Choose the x axis
parallel to the line that connects the endpoints of the wire, so
that the y-z plane is a plane of reflection symmetry for the wire.
This means that the...
A quarter circle of radius 227 mm lies on Quadrant II of a
coordinate plane with reference radius at the origin. A rectangle
is attached to the quarter circle at Quadrant I with base at the
x-axis of width equal to 45.6 mm and height same as the radius of
the quarter circle. Another rectangle with inverse dimension as the
previous is attached to the quarter circle at Quadrant III.

A quarter circle of radius 100 mm lies on Quadrant II of a
coordinate plane with
reference radius at the origin. A rectangle is attached to the
quarter circle at Quadrant I
with base at the x-axis of width equal to 25 mm and height same as

Write a C++ program that prompts the user for the radius of a
circle and then calls inline function circleArea to calculate the
area of that circle. It should do it repeatedly until the user
enters -1. Use the constant value 3.14159 for π
Sample:
Enter the radius of your circle (-1 to end): 1
Area of circle with radius 1 is 3.14159
Enter the radius of your circle (-1 to end): 2
Area of circle with radius 2 is...
