What is the equation of a circle that has a center at point T (-3,-1) and passes through the point (1,-6)

First we need to find out the radius of the circle, radius = sqrt[(-5)^2+4^2] = sqrt(41) The equation of a circle that has a center at point T (-3,-1) and passes through the point (1,-6) is (x + 3)^2 + (y + 1)^2 = 41

If the diagonal of a rhombus are 6 and 8, what is the area of the rhombus? **Weegy:** The area is 24. The rhombus is seperated in 4 triangles by the diagonals and each triangle has area equal to: (8/2)*(6/2)/2= 6. The area of eah triangle multiplied by 4 gives the total area: 6*4=24. **User:** A wooden fence 4 feet high and 200 feet long is to be painted.

A wooden fence 4 feet high and 200 feet long is to be painted. The amount of gallons of paint needed if one gallon covers 300 square feet is: (4*200)/300 = 800/300 = 8/3 = 2.7 gallons.

Let x be the measure of the smaller angle, the measure for the bigger one is x + 5.

The angles are complementary, so x + x + 5 = 90

solve the equation we get x = 42.5 degrees.

The smaller angle is 42.5 degrees.

The angles are complementary, so x + x + 5 = 90
