Question

( 360 * 2 * pai * r) +r + r = 100

Answer 1

Step-by-step explanation:

Diameter = 2 x radius of circle

Circumference of Circle = PI x diameter = 2 PI x radius

where PI = PI = 3.141592...

Area of Circle:

area = PI r2

Length of a Circular Arc: (with central angle theta)

if the angle theta is in degrees, then length = theta x (PI/180) x r

if the angle theta is in radians, then length = r x theta

Area of Circle Sector: (with central angle theta)

if the angle theta is in degrees, then area = (theta/360)x PI r2

if the angle theta is in radians, then area = ((theta/(2PI))x PI r2

Equation of Circle: (Cartesian coordinates)

graph circle

for a circle with center (j, k) and radius (r):

(x-j)^2 + (y-k)^2 = r^2

Equation of Circle: (polar coordinates)

for a circle with center (0, 0): r(theta) = radius

for a circle with center with polar coordinates: (c, alpha) and radius a:

r2 - 2cr cos(theta - alpha) + c2 = a2

Equation of a Circle: (parametric coordinates)

for a circle with origin (j, k) and radius r:

x(t) = r cos(t) + j y(t) = r sin(t) + k

parametric unit circle
