The diameter of a circle has endpoints (-2,-6) and (8,-10)

Enter an equation for the circle in standard form.

Solution:

Given that,

The diameter of a circle has endpoints (-2,-6) and (8,-10)

Use the midpoint formula to find center of circle

Radius = distance between center and one of end points

distance between (3 , -8) and (-2 , -6)

Use distance formula

The standard equation of the circle:

Where, (h , k) is the center of circle

Thus the equation of circle is found

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
