The x-intercept will share the same x-value as the center point. The center of the circle is (3, 4) and the circle must touch the x-axis at the point (3, 0) and thus the radius = 4-0= 4. Circumference = 2π r = 2(π)(4) = 8π...

What is the circumference of the circle to the nearest tenth with diameter 0.5unit? Circles and Their Circumference: In two dimensional geometry, a circle is a closed geometrical shape that surrounds a definite point on the plane from all the sides and has a constants dista...
A circle is a planner geometry that is a locus of all points on the plane that has the same distance from a point at the fixed spot. This constant distance is termed as the radius and the fixed point is known as the center of the circle. ...
