If a circle C with radius 1 rolls along the outside of the circle x² + y² = 36, a fixed point P on C traces out a curve called an epicycloid, with parametric equations x = 7 cos(t) − cos(7t), y = 7 sin(t) − sin(7t). Graph the epicycloid.

Find the area it encloses.

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...

Write c code program for the following Write a function, circle, which takes the radius of a circle from the main function and assign the area of the circle to the variable, area, and the perimeter of the circle to the variable, perimeter. Hint: The function should have three variables as input. Since the contents of the variables are to be modified by a function, it is necessary to use pointers. Please type out the full usable program. Thank you.

A circle of radius r has area A = πr2. If a random circle has a radius that is uniformly distributed on the interval (0, 1), what are the mean and variance of the area of the circle? Change the distribution of the radius to an exponential distribution with paramter β = 2. Also find the probability that the area of the circle exceeds 3, if it is known that the area exceeds 2.

1) A circle with a radius of 0.3 meters is placed in the x-y plane in a magnetic field directed in the -z direction. It is wound once and its resistance is 6 Ohms. The initial magnetic field is 0.8 Tesla. The magnetic field is then changed in 0.6 s and the average induced current is 0.04 amps running counter-clockwise. First, find the final magnetic field to needed to induce this average current. Then, the magnetic field (still in the...
